The majority of people function in a relatively healthy manner. What can most strongly diminish their functional capacity?

A. Compensation involves offsetting perceived deficiencies by excelling in other areas. The patient claiming weight gain is due to fluid retention is not trying to make up for a perceived weakness or deficiency; instead, they are explaining their behavior in a way that deflects responsibility.
B. Rationalization is a defense mechanism where a person provides logical or reasonable-sounding explanations for behaviors or situations that are actually motivated by irrational or emotional factors. In this case, the patient who overeats is rationalizing their weight gain by attributing it to fluid retention rather than addressing the underlying issue of overeating. This allows them to avoid facing the real cause of their weight gain.
C. Regression involves reverting to earlier stages of development or behavior when faced with stress. For instance, an adult might act childishly when under pressure. The patient in this scenario is not behaving in a more immature or childlike manner but is rather giving an excuse for their behavior.
D. Projection involves attributing one's own undesirable thoughts or feelings to others. For example, someone who is untrustworthy might accuse others of being untrustworthy. The patient in this scenario is not attributing their own issues to others but is offering an excuse for their own behavior.

A. This definition encompasses the broader concept of mental health, including emotional, psychological, and social well-being.
B. This definition is too narrow and doesn't capture the full spectrum of mental health.
C. This focuses on physical functioning rather than mental well-being.
