Correct Answer: D
Explanation:
The subject of the sentence is a tied-up prisoner trying to escape, so we can infer that we need to pick out an answer choice that means something like escape. "Constrict" may look like a potentially correct answer choice, but "constrict" actually means hamper the movement of or restrict, so it is an antonym of escape and cannot be the correct answer. "Extricate," however, means to release from difficulty or entanglement, and because it best fits the sentence's context, it is the correct answer. As for the other answer choices, "compact" means to make smaller, "abduct" means kidnap, and "censor" means remove any potentially offensive material from.
