Answer: B - Germane is to irrelevant as navigable is to treacherous.
In the first half of the analogy, germane and irrelevant are antonyms. Germane means relevant and useful, not irrelevant. So, look for the answer pair that contains antonyms. In choice A, omniscient and pansophical both mean all-knowing or almighty. They are synonyms, so eliminate that choice. In choice C, someone who is punctilious is very conscientious and socially correct. These are also synonyms, so eliminate that choice. In choice D, pellucid means clear or transparent. These are synonyms, so eliminate that choice also. In choice B, navigable means that something is crossable or passable, not treacherous and difficult to penetrate. Therefore, choice B is correct.
