Answer: Choice (C) is correct.

In the first half of the analogy, mercurial means the same as fickle, or indecisive and unpredictable. So, look for the answer pair that contains synonyms. In choice (A), something that is bromidic lacks originality. Creative is an antonym for bromidic, so eliminate that choice. In choice (B), laconic means concise and to the point, while verbose means wordy and redundant, so eliminate that choice. In choice (D), inimical means hostile and unfriendly, while affable means pleasant and easygoing. The only choice that contains synonyms is (C). Intractable means unruly or difficult to control.
