The right answer is D. all of the above.

The emotional disturbance is the state in which the person perceives a very intense emotion, usually of anger, which affects their behavior and decision making. In a state of anger, the person is more susceptible to impulsive behavior.

Various investigations have shown that people who drive in a state of emotional disturbance are more susceptible to breaking traffic laws, perform the reckless driving behavior and drive at a faster speed.
