Official Explanation :If you look through the answer choices, you'll notice that some choices include
their, whereas other include
its. That pattern is a tip-off that the question is testing
pronoun agreement.
Choice A is incorrect because the pronoun
their does not agree with the singular referent
advertising agency. The word
agency is a tip-off that the question is testing collective nouns, which are always singular.
Choice B is incorrect because
are should be
is. The subject of that verb is
what, which is always singular when it is used as a subject.
Choice C is correct because
depends agrees with its subject,
what, and its agrees with its referent,
an advertising agency.
Choice D is incorrect because
depend should be
depends. A singular verb is required to agree with the subject
what.
Choice E is incorrect because
for cannot be used to begin a subject; the entire construction is grammatically unacceptable.
