In the wake of means following as a result of something. 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: In the wake of can refer to a situation involving following as a result of something.
• Story example: A writer may use In the wake of when describing a situation involving following as a result of something.
• Exam example: When a sentence contains In the wake of, choose the meaning “following as a result of something.”
