Answer: Choice (B) is correct.

In the initial word pair of the analogy, extricate means to free or to extract, as does disentangle. So, look for the synonym pair in the other answer choices. Choice (A) is incorrect because obfuscate means to confuse or complicate, not clarify, or make clear. Choice (C) is incorrect because to remonstrate means to argue or dispute, and to acquiesce means to agree or consent. In choice (D), to sanction means to allow or authorize, not to prohibit. Choice (B) is the only answer pair that contains synonyms. To inundate means to flood or overwhelm, so choice (B) is correct.
