Which term best fits the description of being deeply affected by anger in a situation?

The term that best fits the description of being deeply affected by anger in a situation is "irate." This word specifically denotes a state of intense anger and frustration. When someone is referred to as irate, it conveys that they are not just mildly upset but are experiencing a strong emotional response characterized by rage or fury. This makes it highly relevant to situations where one's anger significantly influences their feelings or actions.

The other terms do not capture this specific emotional intensity. For instance, "pleased" indicates a positive emotional state, which is the opposite of feeling affected by anger. "Unfazed" describes a lack of reaction to a situation, suggesting indifference rather than being influenced by anger. Similarly, "impassive" refers to a person who shows little to no emotion, which again contrasts sharply with being deeply affected by anger. Thus, "irate" is the most accurate term to describe being profoundly impacted by anger in a given scenario.
