Card players who attribute their wins to their own skill and their losses to bad luck BEST illustrate a bias.

A. The spotlight effect.

B. A self-serving bias.

C. Reciprocal determinism.

D. Unconditional positive regard.

The correct answer to this question is A self-serving bias

Explanation:

In general, the word bias refers to misconceptions about people, practices, issues, etc. In the case of self-serving bias, this occurs when individuals have misconceptions about themselves, especially misconceptions related to positive and negative events. Indeed, this bias makes people believe positive events are the results of inner qualities such as skills or knowledge, while negative events have external causes such as the actions of other people or bad luck. This occurs in the example presented because a positive event (victory) is attributed to inner factors (skills), while a negative event is attributed to something external (bad luck.)
