Card players who attribute their wins to their own skill and their losses to bad luck best illustrate

A) secure self-esteem.
B) reciprocal determinism.
C) the spotlight effect.
D) self-serving bias.

This scenario exemplifies the self-serving bias, which is the tendency for individuals to attribute their successes to internal factors (such as their own abilities or effort) and their failures to external factors (such as luck or situational factors). In this case, the card players attribute their wins to their own skill (internal) and their losses to bad luck (external). This bias helps individuals maintain a positive self-image and protect their self-esteem.
