According to David McClelland, which motivational need involves the desire to lead and influence others?

David McClelland's theory of motivation categorizes individual needs into three primary types: achievement, affiliation, and power. The need for power specifically refers to the desire to lead, influence, and control others, making it the most appropriate choice in this context. Individuals with a high need for power seek positions of authority and often derive satisfaction from engaging others and making impactful decisions. This fundamental desire drives behaviors that aim to attain influence and control in social and organizational settings.

Achievement, on the other hand, relates to the drive to excel and accomplish tasks successfully, focusing more on personal success than on influencing others. Affiliation emphasizes the need for social connections and acceptance among peers, seeking harmonious relationships rather than leading. The term "control," while it might suggest a desire for authority, is not one of McClelland's defined motivational categories, making it less relevant in understanding his framework on motivational needs. Thus, the correct answer aligns closely with McClelland's understanding of the power motive in leadership and influence.
