Answer: Choice (D) is correct.

In the first half of the analogy, meticulous and fastidious are synonyms that mean painstaking and careful. In choice (A), nugatory means inconsequential, not critical, so eliminate that choice. In choice (B), invidious means offensive or obnoxious, not benign or caring. In choice (C), erratic means unpredictable, not stable, so eliminate that choice. In choice (D), someone who is circumspect is cautious or careful.
