Have the last word means make the final decision or final remark. 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 the last word can refer to a situation involving make the final decision or final remark.
• Story example: A writer may use Have the last word when describing a situation involving make the final decision or final remark.
• Exam example: When a sentence contains Have the last word, choose the meaning “make the final decision or final remark.”
