Final answer:
The coach fell into the trap of Premature Focus by assuming the client is a sugar addict without exploring the situation further.
Step-by-step explanation:
The coach in this scenario fell into the trap of Premature Focus. Instead of exploring the client's relationship with candy further, the coach immediately jumped to the assumption that the client may be a sugar addict. It would have been more effective for the coach to ask open-ended questions to better understand the client's motivations and triggers for consuming candy. By prematurely labeling the client as a sugar addict, the coach may have hindered the client's progress by overlooking other factors that could be influencing their behavior.
