Keep a low profile means avoid attracting attention. 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: Keep a low profile can refer to a situation involving avoid attracting attention.
• Story example: A writer may use Keep a low profile when describing a situation involving avoid attracting attention.
• Exam example: When a sentence contains Keep a low profile, choose the meaning “avoid attracting attention.”
