भारतातील घटनादुरुस्ती प्रक्रियेविषयी पुढीलपैकी कोणते विधान अयोग्य आहे ?

The correct answer is Option C (The constitution amendment bill requires previous sanction of the President before its introduction.).

Key Points:
• Procedure for Constitutional Amendment under Article 368:
• Introduction: A Constitutional Amendment Bill can be introduced in either House of Parliament (Lok Sabha or Rajya Sabha), but not in state legislatures. Hence, (1) is correct.
• Presidential Assent: The 24th Constitutional Amendment Act, 1971 made it obligatory for the President to give assent to a Constitutional Amendment Bill (President can neither withhold assent nor return it). Hence, (2) is correct.
• Prior Recommendation: A constitutional amendment bill does NOT require prior permission or sanction of the President before introduction. Hence, statement (3) is false/incorrect.
• No Joint Sitting: Each house must pass the bill separately by a special majority; there is no provision for a joint sitting of both houses in case of deadlock under Article 368. Hence, (4) is correct.
• Therefore, statement (3) is the incorrect one.
• Key Takeaway: Constitutional amendment bills do not require prior Presidential recommendation, must be passed separately by each House, and President must give assent.
