Answer: Choice (C) is the correct answer.

Crescendo means to gradually become louder, and diminuendo means to gradually become softer, so those words are antonyms. So, look for the answer choice pair that are opposites. Adagio and lento both mean a slow tempo, as do largo and grave, so answer choices (A) and (B) are incorrect. In choice (D), bass means the lowest male voice, and contralto means the lowest female voice. They do not have the same relationship as the first half of the analogy, so eliminate that choice.
