Correct Answer: Hesitant

Solution : The correct choice is the second option.

Reluctant means being unwilling or hesitant to do something. When someone is reluctant, they might be resistant or unwilling due to various reasons. The word hesitant describes a state of uncertainty or indecision before taking action.

Both words convey a sense of not being fully committed or enthusiastic about a course of action.

The meanings of the other options are as follows:

• Definite: This term refers to something that is clear, certain, or free from doubt. 
• Indiscreet: This word describes a lack of good judgement or carefulness, often resulting in saying or doing something that is imprudent or tactless.
• Confident: This word represents a feeling of self-assurance, trust, or certainty in one's abilities, decisions, or beliefs. 

Therefore, the most appropriate synonym is hesitant.
