Which definition best describes "intimate"?

The definition that best describes "intimate" is found in choice C, which refers to a close physical proximity. The term "intimate" encompasses feelings and relationships that are deeply personal and close, whether it pertains to friendships, romantic connections, or even a sense of familiarity. The word often connotes not just physical closeness but emotional closeness as well, suggesting a bond that is characterized by warmth, affection, and a level of privacy that is typically reserved for those in close relationships.

Intimacy involves a stronger, more nuanced connection that goes beyond merely expressing feelings or existing in agreement.
