D

Explanation:
Extrinsic rewards are tangible benefits provided by an external source, typically the employer, and are outside the individual’s control. Examples include salary, bonuses, or company cars, which depend on decisions made by others, such as the individual’s boss. Options A (a sense of achievement), B (pride in doing the work), and C (a sense of responsibility) are intrinsic rewards, as they stem from internal feelings of satisfaction and personal accomplishment. The document explicitly states that extrinsic rewards are outside the control of the individual, confirming option D as the correct answer.
