Final answer:
A team leading a major project with significant organizational impact holds legitimate power, which is power authorized by the organization's rules and structure, and is necessary for the successful management of the client project. Option A is correct.
Step-by-step explanation:
A team that has been put in charge of a major project involving a client, which is the largest source of revenue and affects the work of several other teams in the organization, would hold legitimate power. According to sociologist Max Weber, legitimate power is also known as rational-legal authority, which is power legitimized by rules, regulations, and laws.
Since the team's power comes from the formal position of overseeing this major project and because the stability of the organization is connected to the success of the project, the team has been granted legitimate, accepted power. The team has authority as they are recognized within the organizational structure as having the right to manage this project, and their decisions would generally be perceived as official and to the benefit of the organization.
The correct answer to the question is A. Legitimate power.
