(B) is correct.
Ah, an orientation question. As with any orientation question, go through the constraints one at a time and see which answer choice(s) can be eliminated. The first constraint tells us that at least one dessert, one main course, and one side dish must be represented. All five answer choices follow this constraint; let’s move on to the next rule. This one tells us that we need at least one hot food; (E) violates that rule. (D) violates the following rule (if P or W is selected, both must be selected). The next rule says that if G is selected, O also must be selected. Answer choice (C) contains G but no O; eliminate this answer choice. We are left with answer choices (A) and (B). (A) violates the rule that if N is selected, V is out. We are left with (B), which is the correct answer.
