Answer :
An intense emotional state in response to imminent or actual threat is defined as anxiety, a condition that includes psychological and physiological responses to perceived dangers and can lead to traumatic stress.
The intense emotional state that occurs when a threat is imminent or actually occurring is most accurately termed anxiety. This is a psychological state that can last from several seconds to days, characterized by the feeling of reliving a traumatic event as if it were happening in the present moment. Anxiety is often a response to perceived threats to well-being, leading to traumatic stress in extreme situations such as major accidents, wars, assaults, or natural disasters. The physiological response to such threats prepares the body to deal with potential danger, which includes both a psychological and physical state of heightened emotional instability, including feelings of anger, anxiety, or depression.
