Columnist: The idea that many historical events can be explained by postulating as yet undiscovered conspiracies is generally rejected by historians because it is quite unlikely that complex arrangements involving large numbers of conspirators would be kept secret for years. Yet to argue in this way is a mistake. A conspiracy need not be gargantuan and intricate to explain why a country, for instance, decided to act in a certain way: it need involve nothing more than two top decision makers sharing an ulterior motive and keeping it secret.Analysis of the passageThe passage opens by presenting an idea:

B. The first is the conclusion of an argument the columnist purports to refute; the second is the columnist’s conclusion.This choice is completely incorrect because neither boldfaced portion states a conclusion.

Eliminate.
C. The first is a premise the columnist contends is mistakenly thought to support a given conclusion; the second is a conclusion the columnist believes that premise does support.The first part of this choice is correct since the first boldfaced portion is what the historians' use to support their conclusion that it makes sense to reject the idea and since the columnist says that their doing so is "a mistake."
