A poor show means a disappointing performance or result. 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 poor show can refer to a disappointing performance or result.
• Story example: A writer may use A poor show when describing a disappointing performance or result.
• Exam example: When a sentence contains A poor show, choose the meaning “a disappointing performance or result.”
