Exp) Option c is the correct answer

Option c is incorrect. Article 55 of the constitution says that “The election of the President shall be held in accordance with the system of proportional representation by means of the single transferable vote and the voting at such election shall be by secret ballot”. The term preferential or alternative vote system is not used for the election of president in India. However, it was pointed out in the Constituent Assembly that the expression ‘proportional representation’ in the case of presidential election is a misnomer. Proportional representation takes place where two or more seats are to be filled. In case of the President, the vacancy is only one. It could better be called a preferential or alternative vote system. Similarly, the expression ‘single transferable vote’ was also objected on the ground that no voter has a single vote; every voter has plural votes.
