Which of the following represents actions that a leader must take?

The phrase "Be, know, do" encapsulates the essential components of effective leadership. It emphasizes that a leader must embody the qualities and values they expect from others ("Be"), possess the necessary knowledge and skills related to their role ("Know"), and take action to achieve goals and lead their team effectively ("Do"). This triad highlights the importance of personal integrity and accountability in leadership.

While the other choices also reflect important aspects of leadership, they do not capture the foundational principles as comprehensively as "Be, know, do." For example, "Lead, follow, inspire" focuses on relational aspects but does not cover the necessity of knowledge and personal example. "Teach, encourage, mentor" centers on the development of others, which is certainly important, but again lacks the broader scope of self-awareness and action. Lastly, "Plan, organize, execute" stresses practical execution but misses the dimension of personal character and understanding. Thus, "Be, know, do" serves as a holistic framework for leaders, aligning their personal development, knowledge acquisition, and proactive execution.
