First difference in all answer choices is use of Due to or because of.
We know that due to is used when we have to show something is caused by a particular thing.
In the original sentence a reason is provided hence due to options are out of the race.

(A) Because a surfeit of undergraduate students has sent class sizes soaring,
seems fine
(B) Because of soaring class sizes, which is due to a surfeit of undergraduate students,
Which is modifying to class sizes, irrelevant
(C) Because class sizes have been sent soaring, which resulted from a surfeit of undergraduate students,
which is modifying to soaring in addition to this present perfect and simple past making this sentence unnecessary wordy
(D) Due to soaring class sizes from a surfeit of undergraduate students,
As discussed, it is out
(E) Due to a surfeit of undergraduate students, with the result that class sizes have been sent soaring,
Same as D

Hence A seems to be our answer

Hi,

The usage of 'which' always gets me baffled. I am uncertain whether it is modifying the preceding clause/noun and when the usage of 'which' is correct in a sentence. Can anyone please delineate this? Thanks in advance.

Yes! While there are some very rare exceptions to this in official materials, the GMAT is surprisingly consistent in how it uses which: it is used after a comma or a preposition to modify the noun or noun phrase that immediately precedes the comma or preposition. Consider these three examples:

Quote:
The growing season in California, which is a state on the west coast of the US, is getting longer. Correct--which is modifying the noun California

The growing season in California, which has traditionally run from March to November, is getting longer. Correct--which is modifying the noun phrase The growing season in California

The growing season in California is getting longer, which has led to greater water needs. Incorrect--which is trying to modify an entire clause, and by GMAT standards it's not grammatically equipped to do so (though it should be acknowledged that in everyday speech, this usage of which is totally common)

For GMAT purposes, to express the idea that the third (incorrect) sentence is trying to express, a correct answer would probably replace the which clause with a (present) participial phrase:

Quote:
The growing season in California is getting longer, leading to greater water needs. Correct--a present participle (-ing verb) after a comma can modify the nearest verb, its subject, or the entire clause before the comma.

I hope that helps!

Hello Purvidebuka,

We hope this finds you well.

Having gone through your query, we believe we can help resolve your doubt.

On GMAT, the "comma + which" construction always refers to the noun just before the comma. The same also holds for "who", "where", "when", "whose". and "whom" and all phrases constructed around these words, such as "from where", "for whom", etc.

Another thing to keep in mind is the split between "that" and "which". "that" is used to refer to information that is important to the core meaning of the sentence, and the "comma + which" construction is used to refer to extra information.

To understand the concept of "Which/Who/Whose/Where" on GMAT, you may want to watch the following video (~1 minute):


To understand the concept of "Which" versus "That" on GMAT, you may want to watch the following video (~2 minutes):


All the best!
