A cry in the wilderness means a warning or request that nobody listens to. 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 cry in the wilderness can refer to a warning or request that nobody listens to.
• Story example: A writer may use A cry in the wilderness when describing a warning or request that nobody listens to.
• Exam example: When a sentence contains A cry in the wilderness, choose the meaning “a warning or request that nobody listens to.”
