Follow suit means do the same thing as someone else. 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: Follow suit can refer to a situation involving do the same thing as someone else.
• Story example: A writer may use Follow suit when describing a situation involving do the same thing as someone else.
• Exam example: When a sentence contains Follow suit, choose the meaning “do the same thing as someone else.”
