वरीलपैकी कोणते विधान/विधाने बिनचूक आहेत ?

The correct answer is Option C (Both (a) and (b)).

Key Points:
• Post-retirement Practice and Judicial Independence:
• Under Article 220 of the Constitution, a retired permanent judge of a High Court is prohibited from pleading or acting in any court or before any authority in India, except the Supreme Court and the other High Courts (i.e., other than the High Court where he/she served as a permanent judge). Hence, statement (a) is correct.
• Discussion on Conduct of Judges in Legislatures:
• Article 121 and Article 211 prohibit any discussion in Parliament or a State Legislature regarding the conduct of any judge of the Supreme Court or a High Court in the discharge of their duties.
• However, Article 121 explicitly provides an exception: such conduct *can* be discussed upon a motion for presenting an address to the President praying for the removal of the judge (impeachment motion) when it is under consideration in Parliament.
• According to the official answer key, statement (b) is accepted alongside (a), making option 3 the correct key.
• Key Takeaway: Under Article 220, retired HC judges can practice only in the SC and other HCs; conduct can be discussed during impeachment.
