Final answer:
A management coach should be empathetic and supportive, offering constructive feedback and being receptive to receiving feedback themselves. They serve as a guide to help managers create an inspiring and responsive environment for their teams. Therefore, the correct option is D.
Step-by-step explanation:
The most desirable trait in a management coach is to be empathetic and supportive. Rather than talking over clients, a good coach listens more to understand their perspectives and challenges. While brutally honest feedback may sometimes be necessary, it should be delivered constructively and tactfully, not in a way that is harsh, negative, or overly critical. Furthermore, being open to feedback is crucial in the dynamic between a manager and their coach, as it facilitates personal and professional growth. An effective management coach would build a relationship based on trust, provide constructive feedback, and act as a resource for helpful advice. A management coach should also help managers to develop their abilities to inspire their teams, provide clear instructions, and be responsive to their team members' needs for job growth and career development.
