“Pernicious” is an adjective that means gradually harmful over time, so we need to pick out an answer choice that means something like harmful. That means that “beneficial” cannot be the correct answer, because “beneficial” means helpful, making it an antonym, not a synonym, of “pernicious.” “Detrimental,” however, is an adjective that means harmful, and because “detrimental” is the answer choice closest in meaning to “pernicious,” “detrimental” is the correct answer.

"Pejorative" is an adjective that means "expressing contempt or disapproval," so we need to find another word that means about the same thing - roughly, "disapproving." While "sneer" (""a contemptuous or mocking smile, remark, or tone, or to make such an expression or comment") might seem like a good answer because a sneer is often a pejorative gesture, it is not an adjective that means "disapproving," so it can't be the correct answer. "Deprecatory," on the other hand, is an adjective that means "showing a critical or disrespectful attitude," and because it is the answer choice closest in meaning to "pejorative," it is the correct answer.
