How does the individual feel when experiencing stress?

When an individual is experiencing stress, feelings of nervousness and worry are common manifestations. Stress activates the body's fight-or-flight response, leading to physiological and psychological reactions that often result in anxiety. This state of heightened alertness can provoke feelings of fear about an upcoming event or concern over one's ability to manage the pressures being faced.

In moments of stress, the mind may dwell on potential negative outcomes, leading to a focus on what could go wrong, which is characteristic of nervousness and worry. This experience can vary widely from person to person, but the central theme of anxiety in response to stress is a widely observed phenomenon. Therefore, the correct answer captures the essence of how many individuals react emotionally when under stress.
