Answer:
a supportive leader
Step-by-step explanation:
A supportive leader is a leader who is able to identify changes and assistance that are needed to promote the well-being of his team members and timely resolve all unnecessary issues with the aim of delivering a high standard of performance.
A supportive leader is usually kind, friendly, and concerned about the personal needs and welfare of his followers. He also leaves his door open to be approached by many people for advice and help, and also inspires them perform tasks assigned to them with enthusiasm.
Therefore, Peter's behavior implies that he is most likely a supportive leader.
