Simply because is the right answer

Well even though this is not a super tough question, you can learn a lot from this one: how to attack a question (easy or difficult), how to disentagle a possible pitfall, and so forth

Remember : the best strategy is as soos as you read along the way the entire question (is important to read the WHOLE question as it is) to spot the error already from the forst underlined words. So let go and analize the single answer choices:

A) the cost of which raises water bills high enough so that

the cost of which raises.........even though you do not see an error , is easy to figure out thet is awkward and sound weird. moreover, which you know that 99% of the time is used to refer to its antecedent in the form: X,which......favourite gmat construction

B) at a cost raising water bills so high that

make a lonmg story short: similar to the previous one

C) at a cost which raises water bills high enough so

ditto

E) whose cost will raise water bills high enough so that

whose cost (the cost itself) raise water bills ?? a cost raise the bill ?? well this is fine until now: the cost of both things mentioned earlier in the first part of the sentence. good.

high enough : is weird, wordy really bad as construction....this is main issue with E. It seems that that refers to enough,and this to the bills and this is nonsensical, eventually

D) whose cost will raise water bills so high that

first part as in E but the second part is fine: there is that and that is used for restrictive clause

Quote:
What Is a Restrictive Clause?
A restrictive clause is a clause which functions as an adjective to identify the word it modifies. A restrictive clause is essential for the intended meaning. A restrictive clause is not offset with commas

In E you have high enough so that: wrong

In D you have so high that: right

Do not esitate to ask if something is unclear
