Correct answer: (c) 2 3 4 1
Explanation

2 4 3 1
2 4 3 1 gives Article 67(b) to the Speaker and Article 94 to the Vice-President, which reverses those two offices.
- B
3 2 4 1
3 2 4 1 starts Article 61 as Vice-President removal. Article 61 is impeachment of the President.

2 3 4 1 is the match: Article 61 — impeachment of the President; 67(b) — removal of the Vice-President; 94 — removal of the Speaker (and Deputy Speaker); 90 — removal of the Deputy Chairman of Rajya Sabha. That is the official key.
