Final answer:
Attributing success to internal factors typically leads to a feeling of confidence, as it reinforces one's self-efficacy and contributes to a positive self-concept.
Step-by-step explanation:
Attributing success to internal factors, such as one's own abilities or efforts, typically leads to a feeling of confidence. This is because you are recognizing your own role in achieving a positive outcome, which reinforces your self-efficacy and contributes to a stronger self-concept. In contrast, attributions that lead to feelings of shame or guilt are often associated with failures or mistakes, and acknowledging the role of external factors might foster gratitude when outcomes are favorable despite one's limited direct control. Thus, the emotion that is associated with attributing success to an internal factor is confidence (C).
