Which term describes something that motivates people to take action?

• A. Incidence
• B. Impromptu
• C. Inclination
• D. Incentive

Answer: (D)

Motivation to act comes from an incentive—the factor that spurs someone to do something, often a reward or benefit. An incentive directly describes what prompts a person to take action, like a bonus for meeting a target or a discount that encourages a purchase. The other terms don’t convey that prompting push as precisely: incidence refers to how often something happens; impromptu means done spontaneously without planning; inclination is a natural tendency or preference, which may lead to action but isn’t itself the motivating push. So, the best term for something that motivates people to take action is incentive.
