Die hard means disappear or change very slowly. 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: Die hard can refer to a situation involving disappear or change very slowly.
• Story example: A writer may use Die hard when describing a situation involving disappear or change very slowly.
• Exam example: When a sentence contains Die hard, choose the meaning “disappear or change very slowly.”
