Something that encourages action or effort such as a reward.

• A. Motivation
• B. Coercion
• C. Punishment
• D. Incentive

Answer: (D)

An incentive is something that encourages action by offering a benefit or reward. It works by making the payoff of taking a certain action more attractive, so people are more likely to choose that action. Motivation describes the overall drive to act, but incentives are specific prompts that trigger that action in response to a potential gain. Coercion uses threats or force to compel behavior, not to encourage voluntary effort. Punishment aims to decrease a behavior by applying a negative consequence, not to promote it. Because this item points to a thing that prompts action and is commonly framed as a reward, the best fit is incentive.
