Which of the following describes the term "curtly"?

The term "curtly" refers to a manner of communication that is brief to the point of being rude or abrupt. This choice captures the essence of the word, which implies a lack of warmth or friendliness in the response. When someone speaks curtly, they may convey their message in a short, clipped manner that can come across as dismissive or unwelcoming.

The other options highlight positive or neutral forms of communication, such as being warm and friendly, polite, or extended with detail. Each of these contrast sharply with the implication of curt communication, which lacks the courtesy and engagement typically associated with respectful interactions.
