I think the answer is A for two reasons. First, the subject, 75%, is singular. Second, which refers to "glaciares", which is a plural.

Dear Friends,

Here is a detailed explanation to this question-

Choice A:  This answer choice maintains proper subject-verb agreement throughout the sentence and appropriately links the independent and dependent clauses with a comma followed by the word "which". Thus, this answer choice is correct.

Choice B:  This answer choice features a subject-verb disagreement between the noun "glaciers" and the verb "covers". Thus, this answer choice is incorrect.

Choice C:  This answer choice repeats the error seen in Option B. Additionally this answer choice incorrectly precedes "that" with a comma. Thus, this answer choice is incorrect.

Choice D:  This answer choice features a subject-verb disagreement between the noun "seventy-five percent" and the verb "are". Thus, this answer choice is incorrect.

Choice E:  This answer choice repeats the subject-verb disagreements seen in Options D, B, and C. Thus, this answer choice is incorrect.

Hence, A is the best answer choice.

Hi, let me attempt:
 which  after a comma almost always refers to the noun immediately preceding it. In this case which refers to glaciers (plural noun). Therefore, singular verb covers is wrong.
Hope the explanation is helpful!
