Which statement most accurately reflects Mr. Milton's confidence level?

The statement that Mr. Milton shows a lack of confidence is the most accurate reflection of his confidence level if his actions, behaviors, or verbal cues indicate hesitancy, anxiety, or uncertainty in situations. This often manifests through body language, such as avoiding eye contact, fidgeting, or speaking softly, as well as hesitancy in making decisions or expressing opinions.

In contrast, strong confidence would suggest that he is assertive and self-assured in various situations, while being overly confident would indicate a level of assurance that surpasses what is typical or reasonable. The option about being confident only in familiar settings implies that he has some confidence but is limited to those contexts. If Mr. Milton's behavior indicates a pervasive lack of self-assurance rather than variability depending on the environment, then the assertion of a lack of confidence stands out as the most fitting description of his overall disposition.
