A safe pair of hands means a reliable person who can be trusted with responsibility. 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: A safe pair of hands can refer to a reliable person who can be trusted with responsibility.
• Story example: A writer may use A safe pair of hands when describing a reliable person who can be trusted with responsibility.
• Exam example: When a sentence contains A safe pair of hands, choose the meaning “a reliable person who can be trusted with responsibility.”
