Cause a stir means create excitement, surprise, or public discussion. 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: Cause a stir can refer to a situation involving create excitement, surprise, or public discussion.
• Story example: A writer may use Cause a stir when describing a situation involving create excitement, surprise, or public discussion.
• Exam example: When a sentence contains Cause a stir, choose the meaning “create excitement, surprise, or public discussion.”
