The correct answer is: D. intrinsic motivation
Intrinsic motivation is a type of motivation that comes from within the individual. It is based on personal interests, enjoyment, and satisfaction. Intrinsically motivated people are motivated to do something because they enjoy it, not because they are being rewarded or punished.
Extrinsic motivation, on the other hand, is based on external factors, such as rewards or punishments. People who are extrinsically motivated are motivated to do something because they want to get something out of it, such as a good grade or a promotion.
Positive motivation is a type of motivation that is based on the expectation of positive outcomes. People who are positively motivated are motivated to do something because they believe that it will lead to something good, such as success or happiness.
Negative motivation is a type of motivation that is based on the expectation of negative outcomes. People who are negatively motivated are motivated to do something because they believe that it will prevent something bad from happening, such as failure or pain.
In the context of the question, the motivation available at the time of performance of work is intrinsic motivation. This is because intrinsic motivation is based on personal interests, enjoyment, and satisfaction. When people are intrinsically motivated, they are more likely to be engaged in their work and to perform at a high level.
