petulant : affable ::
  1. volatile : capricious
  2. febrile : feverish
  3. noxious : deleterious
  4. nefarious : reputable
Explanation
Answer: Choice (D) is correct.

In choice (A), volatile and capricious are synonyms meaning impulsive and explosive. They are not antonyms, so eliminate that choice. In choice (B), something that is febrile has a fever; these are synonymous, so eliminate that choice. In choice (C), something that is noxious is harmful or injurious - another word for deleterious. These are synonyms, so eliminate that choice. In choice (D), the word nefarious means wicked or despicable, not reputable or highly regarded. These are antonyms, so choice (D) is correct.
