provident : ill-prepared ::
  1. crestfallen : dejected
  2. dauntless : bold
  3. diffident : brazen
  4. esoteric : obscure
Explanation
Answer: Choice (C) is correct.

In the first half of the analogy, provident means visionary and far-seeing, not ill-prepared. So, select the answer choice that contains antonyms. In choice (A), someone who is crestfallen is disappointed and dejected, so eliminate that choice. In choice (B), someone who is dauntless is bold and confident, so eliminate that choice. In choice (C), something that is esoteric is obscure and mysterious, so eliminate that choice. The only choice that contains antonyms is choice (C). Someone who is diffident is shy and reserved, not brazen and bold.
