Good riddance means relief that someone or something unwanted is gone. 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: Good riddance can refer to a situation involving relief that someone or something unwanted is gone.
• Story example: A writer may use Good riddance when describing a situation involving relief that someone or something unwanted is gone.
• Exam example: When a sentence contains Good riddance, choose the meaning “relief that someone or something unwanted is gone.”
