For all intents and purposes means in all practical ways. 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: For all intents and purposes can refer to a situation involving in all practical ways.
• Story example: A writer may use For all intents and purposes when describing a situation involving in all practical ways.
• Exam example: When a sentence contains For all intents and purposes, choose the meaning “in all practical ways.”
