The correct answer is C. Bandwagon appeal

Explanation:

A fallacy refers to a statement in which the reasoning or arguments provided have mistakes or are faulty, despite they may look as valid. Considering there are different issues that occur during the process of argumentation and reasoning there are also multiple fallacies, for example, the hasty generalization, bandwagon fallacy or appeal or the red herring fallacy. In the case of the bandwagon appeal, this fallacy occurs when the speaker or writer conclude something is true just because a lot of people believe it or support the idea.

This is the case of the sentence “Famous singers stay at our hotel; so should you!” in which the author tries to persuade the audience by stating they should stay in the hotel just because many other people and especially famous people have stayed there. Therefore the logical fallacy is the bandwagon appeal or bandwagon fallacy.
