What does it mean to be "leery"?

To be "leery" means to be cautious or wary about something, often due to a sense of suspicion or distrust. It suggests that a person is hesitant to fully engage or involve themselves because they perceive potential danger or deceit in a situation or from a person. For example, if someone is leery of a business deal, they might have doubts and prefer to tread carefully before making a commitment. This word is frequently used to convey a sense of vigilance and caution, making it the most fitting interpretation compared to the other choices, which do not capture that sense of caution and skepticism.
