Which word describes a state of being very angry?

The word that accurately describes a state of being very angry is "irate." This term specifically conveys intense anger, often in a context where an individual reacts with outrage or frustration. It captures the emotional state effectively, indicating not just mild annoyance but a more extreme and vigorous response to a situation.

In contrast, the other options suggest a lack of strong emotional agitation. "Calm" implies a peaceful and tranquil state, "passive" denotes an absence of active resistance or emotion, and "composed" suggests a state of being collected and self-controlled, often in the face of potential upheaval. None of these words convey the depth of anger that "irate" does, making it the most suitable choice for describing a state of being very angry.
