Which term is used to describe 'A person who stands out negatively within a group'?

• A. Black Sheep
• B. Red Letter Day
• C. Idiom
• D. Metaphor

Answer: (A)

The main idea here is using a common phrase to describe someone who stands out in a negative way within a group. The phrase that best fits is the one that directly labels a person as an outlier who isn’t conforming in a way that reflects poorly on the group.

This expression describes exactly that idea: a member who stands apart in a negative sense, often seen as not fitting in or bringing trouble to the group. It comes from the historical fact that black sheep were once considered less valuable than white sheep, so the term has carried the connotation of outsider or misfit within a family or circle.

For contrast, a red letter day refers to a particularly memorable or fortunate day, not to a person. An idiom and a metaphor are categories of figures of speech, not specific labels for someone who stands out negatively.
