According to Self-Discrepancy Theory, your self-esteem is highest when A. Your self-concept matches your ideal and ought selves.
This theory posits that self-esteem is influenced by the degree of discrepancy between the actual self and the ideal (what one aspires to be) and ought (what one believes they should be) selves. When there is a match between one's self-concept and these standards, self-esteem is likely to be at its highest.
