Asking irrelevant questions is usually evidence of:

The act of asking irrelevant questions typically serves as a mechanism for individuals to gain attention. When someone poses questions that are not pertinent to the discussion, it can divert focus toward themselves rather than the subject at hand. This behavior suggests a desire for engagement, recognition, or validation from others. People may resort to such tactics when they feel overlooked or when they want to assert their presence in a conversation. It is a way to elicit reactions from the audience, thereby satisfying a need for attention and affirmation.

In context, the other options reflect different motivations that do not align as closely with the behavior of asking irrelevant questions. For instance, power seeking generally involves more direct strategies aimed at control or dominance, rather than simply diverting attention. Revenge seeking typically manifests through antagonistic or confrontational actions, which are also distinct from the casual nature of irrelevant questioning. Feeling inadequate may lead to self-doubt or withdrawal rather than the active pursuit of attention that comes with asking off-topic questions. Therefore, the most fitting motivation behind irrelevant questioning is indeed the pursuit of attention.
