If someone shows "defiance", how are they behaving?

When someone shows "defiance," they are exhibiting behavior characterized by resistance or disobedience, particularly towards authority or established rules. This behavior can manifest as an outright refusal to comply with requests, instructions, or expectations. Defiance often involves an attitude of rebellion, where the individual may actively challenge or confront authority figures rather than simply ignoring them.

This understanding aligns well with the context of the word "defiance," which implies a clear stance against submission or obedience. The choice indicating a refusal to obey accurately captures this essence, portraying the individual as actively opposing directives rather than cooperating or agreeing with them.
