Explication
Facetious means treating serious issues with deliberately inappropriate humour or being flippant. It suggests that someone is not being serious. This means that "unserious" is the answer to this question.
Crazy means being mentally unstable or wild. Serious is the opposite of facetious. Unfaithful means being disloyal, particularly in a romantic relationship.
