Who seems to have a protective role based on their statement regarding a "big baby"?

The correct choice highlights a character who takes on a protective role, particularly as indicated by their reference to a "big baby." This phrase suggests an intention to look after someone who may be perceived as vulnerable or in need of care. The character's statement implies a level of concern or responsibility for the well-being of another, reinforcing their protective demeanor.

In the context of the story, this characterization is significant as it showcases dynamics of care, support, and the relationships between the characters. The imagery of a "big baby" might convey not only affection but also a willingness to safeguard and aid someone who may be struggling or less self-sufficient.
