When someone acts "warily", how are they behaving?

When someone acts "warily," they are behaving with great care. This term implies a cautious approach, where an individual is being watchful and careful due to a potential risk or uncertainty in their environment. For instance, if a person is walking through an area that might be dangerous, they would tread lightly, paying close attention to their surroundings. This carefulness is rooted in the need to avoid danger or mistakes, making "with great care" the most appropriate interpretation of the term "warily." The other options suggest behaviors that are more reckless or unconcerned, which do not align with the cautious nature of acting warily.
