Repentance affects man in his:

The correct choice highlights the comprehensive impact of repentance on a person's inner life, specifically targeting the mind, emotions, and will.

Repentance is a transformational process that involves deep reflection and change in one's beliefs and attitudes. The mind is where the understanding and acknowledgment of wrongdoing take place, prompting a shift in perspective. In terms of emotions, repentance often involves feelings of sorrow for past actions and a desire for reconciliation. This emotional aspect is critical as it drives the individual towards seeking forgiveness and making amends. Lastly, the will represents the person's intention and decision-making capacity to turn away from sinful behaviors and make a conscious choice to pursue a different path aligned with spiritual values.

While the other answer choices encapsulate important aspects of human experience, they do not reflect the most direct components influenced by repentance. The suggestion of heart and body in another choice could imply physical actions or feelings but lacks the emphasis on the decision-making process and emotional aspect that is central to true repentance. Similarly, thought, action, and speech, though relevant, do not capture the depth of internal change that repentance entails in the mind, emotions, and will. Finally, spirit, mind, and heart might convey a spiritual transformation but do not specifically address the emotional and volitional factors
