Which characteristic is associated with being reticent?

Being reticent refers to the quality of being reserved or reluctant to speak or engage in conversation. This characteristic often manifests as a tendency to hold back thoughts and feelings, making individuals appear quiet or introverted. This aligns directly with the notion of being reserved, which encapsulates the essence of reticence.

In contrast, being overly expressive, charming, or outgoing involves an openness and willingness to communicate freely, which contradicts the definition of reticent. Therefore, the correct answer emphasizes a demeanor that favors discretion and restraint, aptly describing what it means to be reticent.
