In the red means in debt or losing money. This answer is correct because the expression has a fixed figurative meaning in English. In an SSC idiom question, students should match the whole phrase with its accepted meaning rather than translate each word separately.

• Classroom example: In the red can refer to a situation involving in debt or losing money.
• Story example: A writer may use In the red when describing a situation involving in debt or losing money.
• Exam example: When a sentence contains In the red, choose the meaning “in debt or losing money.”
