Answer:

A. Agitation

• Agitation is a state of anxiety or nervous excitement.

• Agitation means that a person is restless or worried. He or she doesn't seem to be able to settle down. Agitation may cause pacing, sleeplessness, or aggression, which is when a person lashes out verbally or tries to hit or hurt someone.

• Agitation is a sense of inner tension and restlessness. When it happens, you may get annoyed easily or feel like you need to move around. It's a normal emotion. But it's more likely to show up when you're under a lot of stress.
