In question means being discussed or doubted. 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 question can refer to a situation involving being discussed or doubted.
• Story example: A writer may use In question when describing a situation involving being discussed or doubted.
• Exam example: When a sentence contains In question, choose the meaning “being discussed or doubted.”
