Answer: Choice (B) is correct.

In the first half of the analogy, consider the relationship of alcove and enclosed. The second word - enclosed - describes the first word. So, select the answer pair in which the words have a similar relationship. In choice (A), a debacle is a disaster or catastrophe, and is not serene or peaceful, so eliminate that choice. In choice (C), someone’s ego might be inflated, but that is not an absolute characteristic, as with alcove and enclosed. In choice (D), a grotto and a cavern are the same thing; they have a synonymous relationship, so eliminate this choice. In choice (B), a lesson is didactic - educational or instructive. Therefore, choice (B) is correct.
