Correct answer: (d) 3 only
Explanation
- A
1 and 2 only
(a) 1 and 2 only. High Court and Supreme Court judges are removed by a parliamentary address (Articles 124(4), 217/218). Parliament does play a role, so they cannot be the ‘no role’ pair.
- B
3 and 4 only
(b) 3 and 4 only. The CAG is removed like a Supreme Court judge, so Parliament does act on 4; bundling CAG with the UPSC Chairman is wrong.
- C
1, 2 and 3 only
(c) 1, 2 and 3 only. 1 and 2 do involve Parliament, so this trio is too wide.
- D
3 only
(d) 3 only. The UPSC Chairman (and members) are removed by the President on a Supreme Court inquiry under Article 317; Parliament has no impeachment-type role. That single official is the official key.
Summary. Official key is (d). Parliament has no role in removing the UPSC Chairman. It does address-remove Supreme Court and High Court judges and the CAG.
