IMO B

A. as using a machine although machines use electricity, require maintenance, and take up space
Incorrect.

We need to compare so usage of than is necessary

B. than using a machine does although machines use electricity, require maintenance, and take up space

Correct .

Rectifies the error by using than .Also uses correct parallelism.(use ,require,take up) all verbs.

C. than using a machine although machines use electricity, require maintenance, and take up space

Incorect.
Even though it rectifies the error by using than ,it does not use " machine does" .Usage of does is essential

D. than using a machine does although machines use electricity, require maintenance, and large spaces
Incorrect.
Large spaces is not parallel to use and require.

E. than using a machine does although machines require maintenance, electrical, and take up space.

Incorrect.
Not parallel.

1. larger ... than is correct idioms
2. parallel - use, require and take up.

Washing dishes by hand uses a much larger amount of water as using a machine although machines use electricity, require maintenance, and take up space.

A. as using a machine although machines use electricity, require maintenance, and take up space: comparison mistake: larger than is correct form

B. than using a machine does although machines use electricity, require maintenance, and take up space: right using correct comparison and parallelism
C. than using a machine although machines use electricity, require maintenance, and take up space: comparing "using a machine" with "washing dishes by hand" is wrong. we want to compare "washing dishes by hand" with "washing dishes by machine". correct conversion of the last one is "using a machine does".
D. than using a machine does although machines use electricity, require maintenance, and large spaces": parallelism mistake: use, require and large spaces /last one should start with verb/
E. than using a machine does although machines require maintenance, electrical, and take up space: parallelism mistake: require, electrical and take up are not parallel.

correct parallelism should use same category of words: verb with verb, adj with adj, adv with adv, noun with noun, clause with clause ect.

OFFICIAL EXPLANATION

Washing dishes by hand uses a much larger amount of water as using a machine although machines use electricity, require maintenance, and take up space.

A. as using a machine although machines use electricity, require maintenance, and take up space

This answer choice is illogical and grammatically incorrect. The word larger (or any adjective+er) cannot be complemented by as because larger indicates an inequality between the two things compared whereas as indicates a similarity between them.

What helps us identify this question as a Comparative question as well as identify the mistake is the following Stop Sign: Like, unlike, than, as

B. than using a machine does although machines use electricity, require maintenance, and take up space

This answer choice corrects the original Comparative error by replacing as with than and adds a conjugated verb in the second part of the comparison, as preferred in the GMAT.

C. than using a machine although machines use electricity, require maintenance, and take up space

Although this answer choice corrects the original Comparative error by replacing as with than, it is not the most stylistically sound. A stylistic preference in Comparative questions is that there should be a conjugated verb in the second part of the Comparative construction (i.e., after the word than).

There is an answer choice that is both grammatically correct and includes a conjugated verb in the second part of the comparison. Look for it!

D. than using a machine does although machines use electricity, require maintenance, and large spaces

Although this answer choice corrects the original Comparative error by replacing as with than, it is grammatically incorrect. The first two items in the list at the end of the sentence are verbs (use, require), but the last item is a noun (spaces).

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

A list of 3 items or more, separated by commas and and/or before the last item.

E. than using a machine does although machines require maintenance, electrical, and take up space

Although this answer choice corrects the original Comparative error by replacing as with than, it is grammatically incorrect. The first and last items in the list at the end of the sentence are verbs (require, take), but the middle item is an adjective (electrical).

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign: A list of 3 items or more, separated by commas and and/or before the last item.

Washing dishes by hand uses a much larger amount of water as using a machine although machines use electricity, require maintenance, and take up space.

A. as using a machine although machines use electricity, require maintenance, and take up space // "a much larger" requires "than"
B. than using a machine does although machines use electricity, require maintenance, and take up space // "does" is unnecessary here and can be omitted.
C. than using a machine although machines use electricity, require maintenance, and take up space // correct
D. than using a machine does although machines use electricity, require maintenance, and large spaces // "does" is unnecessary here and can be omitted.
E. than using a machine does although machines require maintenance, electrical, and take up space // "does" is unnecessary here and can be omitted. "electrical" is an adjective and requires "are". i.e. machines are electrical.

With all due respect, I object to the explanation. Logically, one cannot say that "washing dishes by hand uses a machine" rather than "a machine uses water." Saying "washing dishes by hand uses a much larger than a machine does" is not concise, we can safely omit "does". So, option C is more elegant than option B.

The question tests the concept of comparisons. But, the latter part of the sentence also tests the concept of parallelism. So, we can start eliminating options using either of the concepts.

If we were to take parallelism, the last part of the sentence mentions three things that machines do – “use electricity”, “require maintenance”, take up space”.

Options A, B, and C correctly maintain the parallelism. Option D leaves out the verb before ‘large spaces’, and therefore, is incorrect. Option E changes the form of the second item in the list (“electrical” when it should be “use electricity”) and is also therefore, incorrect.

When we compare Options A, B, and C, we see that B and C start with the transition word ‘than’, whereas, Option A starts with ‘as’. When we refer to the non-underlined portion of the sentence, we can see that the comparative word used is “much larger”, which should be followed by ‘than’ and not ‘as’. So, Option A can also be eliminated.

The difference between Option B and Option C is that the verb ‘does’ is not used in Option C. The verb ‘does’ is necessary to complete the comparison between “washing dishes by hand and using a machine”. "Washing dishes by hand uses a much larger amount of water than using a machine does".

Therefore, Option B is the best answer.

Option B is correct as the quantities being compared in option C are not comparable 'Washing dishes by hand' and 'using a machine'.
Would it have been correct had the sentence been worded as 'Washing dishes by hand uses a much larger amount of water than washing dishes using a machine.' ?
Now the items being compared are comparable items.
