Final answer:
The teen boy's behavior is symptomatic of a psychotic episode, making 'b. Psychosis' the correct answer to the multiple-choice question.
Step-by-step explanation:
The scenario described where a teen boy is knocking over products, throwing canned goods, tearing at his clothing with his teeth, and screaming about alien attacks is an example of psychosis. Psychosis is a mental health problem that causes people to perceive or interpret things differently from those around them. This can include hallucinations or delusions. The behaviors exhibited by the teen, such as the agitation, aggression, and hallucinations (believing aliens are attacking) are symptomatic of a psychotic episode. This means the correct answer to the multiple-choice question is b. Psychosis.
