Answer: Choice (D) is correct.

To appease means to calm, soothe, or pacify, as does placate. So, look for the answer choice that contains a pair of synonyms. Choice (A) is incorrect, because belabor means to insist repeatedly, and disregard means to overlook or ignore. Choice (B) is incorrect, because to obfuscate means to make things confusing or complicated, and to clarify means to make something clear. Choice (C) is incorrect, because to vacillate means to be indecisive or to waver, and that is the opposite of decide. The only answer choice that contains synonyms is choice (D). Obviate and preclude both mean to anticipate and prevent difficulties, so choice (D) is correct.
