The best answer to the query is B. Stepping out of a tactical role to assume a leadership role when needed, developing subordinates for the future, ensuring tasks are understood.
This option demonstrates a leader's commitment to duty in several key ways:
In contrast, the other options demonstrate a lack of commitment to duty:
A indicates a hands-off approach that does not provide necessary support, which can lead to misunderstandings and failures without a constructive outcome.
C involves providing unclear direction, which is counterproductive to effective leadership. It can lead to confusion and does not facilitate development.
D (Management by objectives) can be useful but does not inherently indicate a commitment to duty without specific context; it relates more to a goal-setting framework than direct leadership actions.
Thus, option B clearly aligns with the qualities and responsibilities expected of a committed leader.
