What emotion does "indignation" typically express?

Indignation typically expresses a sense of righteous anger or moral outrage in response to perceived injustice, unfair treatment, or wrongdoing. It arises when someone feels that their values or the rights of others have been violated, prompting an emotional response that can include annoyance, frustration, or a desire for retribution. This emotion is rooted in a strong belief that something is fundamentally wrong and deserving of critique or action. In contrast, the other options reflect emotions that do not capture this sentiment: joy represents a positive feeling, confusion indicates uncertainty, and apathy signifies a lack of interest or concern. Thus, the correct choice aligns tightly with the concept of indignation as a passionate reaction to unfairness.
