“Extant” is an adjective that means “still in existence; surviving,” so we need to pick out an answer choice that means something like “still in existence.” That means that “destroyed” cannot be the correct answer, because “destroyed” is an antonym, not a synonym, of “extant.” “Remaining,” however, when used as an adjective, can mean “still existing, present, or in use; surviving,” and because “remaining” is the answer choice closest in meaning to “extant,” “remaining” is the correct answer.

"Innate" means something naturally present; it is therefore most similar in meaning to “inherent.” For clarification, "introspective" means internally self-reflective; "persuasive" means argues convincingly; "dogged" and "determined" are synonyms.
