Which of the following is NOT a form of power in a business context?

In a business context, the types of power typically recognized include reward power, referent power, and legitimate power. Reward power is derived from the ability to provide benefits or rewards to others, such as promotions or bonuses. Referent power comes from the personal attributes of an individual that others admire or identify with, leading those individuals to follow or support them. Legitimate power is based on a person's formal position within an organization, granting authority due to their role.

Political power, while present in many organizations and important for navigating influence and resource distribution, is not classified in the same way as the other three forms of power. Political power is often more informal and associated with alliances and organization dynamics rather than a clear, definable source of influence. Thus, identifying political power as not being a formal type of power in the conventional sense used in business management differentiates it from reward, referent, and legitimate power, making it the correct answer in this question.
