Final answer:
The coach is using amplified reflection, a technique that exaggerates the client's situation to encourage reevaluation and consideration of potential solutions to manage stress.
Step-by-step explanation:
The coach is demonstrating D. Amplified reflection. This technique involves exaggerating what the client has said, possibly to help the client see the limitations of their viewpoint and consider other perspectives. By stating "So you are stuck. There's absolutely nothing you can do about it," the coach is overstating the client's feeling of being stuck, potentially prompting the client to reassess the situation and think of solutions that had not occurred to them before. To manage stress, it is recommended to adopt problem-focused or emotion-focused coping strategies, which may include engaging in exercise, meditation, relaxation techniques, and promoting psychological readiness and resilience.
