All and sundry means everyone without distinction. 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: All and sundry can refer to a situation involving everyone without distinction.
• Story example: A writer may use All and sundry when describing a situation involving everyone without distinction.
• Exam example: When a sentence contains All and sundry, choose the meaning “everyone without distinction.”
