Have one's way means get what one wants. 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: Have one's way can refer to a situation involving get what one wants.
• Story example: A writer may use Have one's way when describing a situation involving get what one wants.
• Exam example: When a sentence contains Have one's way, choose the meaning “get what one wants.”
