Answer:
The correct answer is c. achievement motivation; competition
Step-by-step explanation:
In psychology, motivation is a certain process where we feel a need to accomplish certain tasks or perform certain actions in order to reach a goal that we find desirable.
One of the things that can motivate us is competition, which refers to a certain situation where we are contesting against other people or against ourselves. When competition is against ourselves, we refer to that as self-competition. Self-competition is a sort of internal incentive, where we challenge ourselves to do better than in the past. This is a form of achievement motivation, where the end goal is not an external reward or evaluation, but the feeling that we have accomplished something. On the other hand, when the competition is against others, that means the incentive to perform is external, and we compete in these socially evaluative situations in order to achieve a reward.
