Which one among the following statements pertaining to the President's term of office is not correct?

According to Article 56 of the Constitution of India, the President holds office for a term of five years from the date of entering office [2]. The President can be removed before the completion of this term through the process of impeachment for 'violation of the Constitution' as prescribed in Article 61 [1]. Furthermore, the President continues to hold office beyond the five-year term until a successor enters upon the office to ensure continuity [4]. However, statement 3 is incorrect because the President's resignation must be addressed in writing to the Vice-President of India, not the Speaker of the Lok Sabha [4]. While the Vice-President is required to communicate this resignation to the Speaker, the letter itself is constitutionally mandated to be addressed to the Vice-President [4].
