भारताच्या राष्ट्रपतीची निवडणूक पद्धत राज्यघटनेत दुरुस्तीद्वारे बदलता येवू शकते, त्यासाठी घटना दुरुस्ती ______ द्वारे मंजूर होणे आवश्यक असते.

The correct answer is Option C (two third majority by both Lok Sabha and Rajya Sabha and be ratified by legislatures of atleast one half of the states.).

Key Points:
• Amendment Procedure under Article 368:
• The election of the President (Articles 54 and 55) is an integral part of India's federal structure because state legislative assemblies are part of the Electoral College.
• Under the proviso to Article 368(2), any amendment affecting:
• Articles 54 and 55 (Election of President),
• Extent of executive powers of Union and States,
• Supreme Court and High Courts,
• Distribution of legislative powers, etc.,
• Requires a Special Majority of Parliament (a majority of the total membership of each House AND a majority of not less than two-thirds of the members present and voting in each House) along with ratification by the legislatures of not less than one-half of the states by simple majority.
• Key Takeaway: Amending the presidential election process requires a special majority of Parliament plus ratification by at least 50% of the state legislatures.
