खालीलपैकी कोणते विधान बरोबर नाही?

The correct answer is Option D (The Constitution has laid down some grounds upon which a Governor may be removed by the President.).

Key Points:
• Statement 4 is incorrect because the Indian Constitution does NOT lay down any specific grounds or procedure for the removal of a Governor by the President under Article 156.
• The Governor holds office purely during the pleasure of the President.
• Statements 1, 2, and 3 are correct descriptions of the Governor's tenure under Article 156.
• Key Takeaway: Constitution provides no specific grounds for Governor's removal by the President.
