Get wind of means hear about something secret or private. 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: Get wind of can refer to a situation involving hear about something secret or private.
• Story example: A writer may use Get wind of when describing a situation involving hear about something secret or private.
• Exam example: When a sentence contains Get wind of, choose the meaning “hear about something secret or private.”
