Answer: The correct answer is D. Keegan screams loudly when his brother startles him.
Explanation: Overt behaviors are a certain type of conduct that can be observed by others. Talking, walking, screaming, laughing, are all examples of overt behaviors.
Covert behaviors are behaviors that can be done in secrecy or privacy and cannot be observed by others. Thinking, feeling, perceiving are all examples of covert behaviors if they are not displayed by the person experiencing them.
In this particular example, the only statement that is an example of overt behavior caused by emotion is:
D. Keegan screams when his brother startles him.
The emotion that Keegan is experiencing is fear and the observable behavior that she displays to express that emotion is screaming.
