How did Pedro demonstrate a defense mechanism after failing his driving test?

Pedro's use of reaction formation as a defense mechanism involves exhibiting behavior that is opposite to what he truly feels. After failing his driving test, he may have acted overly cheerful or expressed an exaggerated sense of confidence, suggesting that the failure did not bother him. This behavior can be a way to mask feelings of disappointment, embarrassment, or frustration that he may actually be experiencing. By displaying a façade of enthusiasm or indifference, he is protecting himself from the emotional pain associated with his failure, thereby using reaction formation to cope with his feelings in a manner that is socially acceptable and less vulnerable.

This understanding of reaction formation helps clarify how individuals may respond to their emotions in ways that seem counterintuitive but serve a purpose in their psychological defense. In contrast, the other options suggest different responses that may not align with the behaviors typically seen in reaction formation.
