Answer:
B. Rhetorical question.
Explanation:
A rhetorical question is a figure of speech used in the form of a question whose point is not to necessarily elicit a response or an answer, but rather to make a point, often trying to signal or evoke an obvious fact that by merely asking about it becomes confirmed. Sometimes, rhetorical questions are also aimed at igniting a discussion around a basic fact that is taken for granted but remains problematic.
