Final answer:
An effective management coach should be empathetic and supportive, listen more than they talk, and provide constructive feedback. They must also be open to feedback to promote a trusting and developmental environment. Thus, the option A is the correct answer.
Step-by-step explanation:
A management coach ideally has several key traits that foster a positive and productive environment for personal and professional growth. Among these traits, being empathetic and supportive stands out as a crucial characteristic. An effective management coach listens more than they talk, providing a sounding board for the individual's thoughts and concerns. Far from being harsh, negative, or overly critical, a good coach offers constructive feedback, not just 'brutally honest' feedback, in a way that is helpful and intended to support improvement. It is imperative for management coach to be open to feedback themselves, as this builds trust and demonstrates their commitment to learning and development.
