Answer:
4) Reward power
Step-by-step explanation:
Reward power in management refers to the power that a manager possesses to hand out rewards to his/her subordinates in order to influence their task performance or behavior. Rewards are not only monetary (e.g. $$$ or promotions), they can also include goods (e.g. a watch, golden pin, etc) or other intangible rewards (e.g. praise, public recognition, time off work, etc.).
Usually employees that perform their tasks in an efficient manner should be rewarded, and that should inspire his/her coworkers to do the same.
