Answer: Choice (B) is correct.

In the first half of the analogy, something that is sinuous is winding, supple, and lithe. So, look for the answer pair that contains synonyms. In choice (A), someone who is furtive is secretive and sneaky, not overt and open, so eliminate that choice. In choice (C), someone who is officious is intrusive and overbearing - far past merely being eager. In choice (D), something that is pellucid is transparent, not opaque, so eliminate that choice. The only choice that contains synonyms is choice (B). Someone who is indulgent is lenient and tolerant, so that is the correct choice.
