In which context would the word 'frigid' most likely be used?

The word 'frigid' is most commonly used to describe something that is very cold in temperature, but it can also extend to emotions and interactions. In the context of an unwelcoming environment, 'frigid' conveys a sense of emotional coldness or a lack of warmth, both literally and figuratively. It aptly captures a setting where feelings of discomfort or hostility prevail, contrasting sharply with warmth and friendliness. This makes it an ideal choice for describing a cold or unwelcoming atmosphere, illustrating how the term can evoke feelings of isolation or unapproachability, be it in a physical space or in interpersonal relationships.

While the other contexts may have association with emotions, 'frigid' specifically aligns with the concept of coldness, making option C the best fit. A friendly atmosphere would contradict the meaning of frigid, a romantic relationship suggests warmth and affection, and discussions of financial stability are unrelated to the emotional or physical temperature implied by the word.
