Answer:
C. positive incentive
Explanation:
The positive incentive consists in increasing the frequency of a behavior caused by the addition of some benefit that would be the result of that behavior. It is the stimulus to a behavior that did not exist before the event occurred. For example, disability pension stipulation is an event that benefits the disabled. However, the existence of this benefit may encourage behavior (which previously did not exist) in people who are not disabled to say they are.
