Which of the following is NOT one of the three powers of the head of government?

The head of government primarily exercises three main powers: legislative power, military power, and executive power. Legislative power involves the ability to influence or initiate laws. Military power refers to the authority over the armed forces and aspects of national defense. Executive power encompasses the enforcement of laws and the administration of governmental operations.

The characterization of diplomatic power as a separate power may lead to confusion. While heads of government do engage in diplomacy, it falls under the broader scope of executive power, where they manage foreign affairs and represent the state in international relations. Therefore, diplomatic power is not considered one of the primary powers in the same way as legislative, military, and executive powers are. This distinction clarifies why diplomatic power is not listed among the three core powers of the head of government.
