if subjects (X and Y) are placed in Either X or Y type of construction then the closest subject decides the singular or plural form of verb.

The department chair is singular and closest to the verb. thus, verb must be posts not post. Therefore, E is wrong.
If you want to learn how verb depends on subject in either .. or construction check link Mike has provided above.
Or you can refer chapter 3, MGMAT SC, page 44.

Official Explanation


Split #1: SVA. This is an OR subject. In the first three choices, the second term, “the members,” is plural, so we need a plural verb. Choice (C) makes a SVA mistake.

In the last two choices, the second term, “the department chair,” is singular, so we need a singular verb. Choice (E) makes a SVA mistake.

Split #2a: Pronoun problem. After the comma, the “it” is meant to refer to the “challenge problem,” but could refer to “the student body.” This is a pronoun with ambiguous antecedent. We need to restate the noun, “the problem.” Choices (A) & (D) make this mistake.

Split #2b: Pronoun problem. The “they” is meant to refer to the students, but “student body” is singular collective noun. The only plural noun is “the faculty members,” but it would be illogical for the pronoun to refer to them. The “they” is wrong, and choices (A) & (C) & (D) make this mistake.

Choice (B) is the only possible answer.
