I can tell that B is wrong, since the ‘pronoun ‘they’ has no noun to refer to. This is also true for option E and the pronoun ‘them’. ‘Student enrollments of 70%’ is an incorrect phrase that does not make sense, so A is wrong too. ‘Which has’ in option D is also an incorrect phrase. So, C is the right answer.

Can you pls explain how D is better than C

Though C absolutely makes sense, I have read it in many questions that "where" should be used for physical places

Hello again, GDT. I think VeritasKarishma has done a fine job above discussing how where is a stand-in for in which here. I prefer the latter, so I immediately looked at (E). But other issues prevented me from choosing it. To answer your query, I cannot explain how (D) is better than (C), since (C) is the better option, but we will look at the two side by side in the context of the surrounding sentence:

(C) The rapid population growth within the boundaries of the Springfield Public School district was a source of an overcrowded school system where 70 percent of student enrollments are above the state board of education's suggested limits.

(D) The rapid population growth within the boundaries of the Springfield Public School district was a source of an overcrowded school system which has 70 percent of student enrollments above the state board of education's suggested limits.

To be honest, I wanted are at the end of (C) to read were instead (to agree with the earlier was in was a source). In addition, I wanted where to read in which, but I held on to (C) because I could not argue against it outright.

In (D), the restrictive which clause is okay. I read it as a that. The part that deterred me from choosing it was the phrase has 70 percent of... enrollments above, a less clear and direct version of 70 percent of... enrollments are above from the previous answer choice. (Note, too, that has did not address my concern in (C) about verb tense.) In all, clarity of meaning guided me to (C) as the harder to argue against. I am not crazy about either answer, as I never like to choose something based on what I want to see, but between the two options, (D) is harder to follow.

I hope that helps. Learn what you can from such questions.

- Andrew

The rapid population growth within the boundaries of the Springfield Public School district was a source of an overcrowded school system where the student enrollments of 70 percent of them are above the state board of education's suggested limits.

A.where the student enrollments of 70 percent of them are
B.where they have 70 percent of student enrollments
C.where 70 percent of student enrollments are
D.which has 70 percent of student enrollments
E.in which 70 percent of them have student enrollments

I belive the best way to solve this problem is focusing on the intended meaning.

What is above the state board of education limit? A RATIO of 70% of enrollments of a total of student . In fact for this reason, which is the fact that more students than the limit have been enrolled, the schools became overcrowded.

Thus, that said, we can see that

A out because the antecedent of the pronoun THEM has not a clear antecedent. It appears linked to the enrollments rather than the students and for this reason it changes the meaning because it means that only the enrollments rather than the ratio of 70% are above the limit and it logically does not make any sense or it is not the intended meaning of the original clause
B out because of what said above + they doesn't have a clear antecedent
C This seems to refer more to the ratio that each of the enrollments + no ambiguity in any pronoun, let's keep it
D out because here also the enrollments (each of them) is above the limits rather then the ratio
E out because them has no antecedent

Thus C
