Exp) Option c is the correct answer.

The President is elected not directly by the people but by members of specially constituted Electoral College.

Statement 1 is correct: The Constitution provides that there shall be uniformity in the scale of representation of different states as well as parity between the states as a whole and the Union at the election of the President. To achieve this, the number of votes which each elected member of the legislative assembly of each state is entitled to cast at such election shall be determined in the following manner: Every elected member of the legislative assembly of a state shall have as many votes as there are multiples of one thousand in the quotient obtained by dividing the population of the state by the total number of the elected members of the assembly.

Statement 2 is correct: The elected members of legislative assembly of Union territory of Delhi participate in Presidential election. Apart from this, elected members of both the Houses of Parliament, legislative assemblies of the states and the elected members of the legislative assemblies of the Union of Puducherry also participate in the election of President. Thus, the nominated members of both of Houses of Parliament, the nominated members of the state legislative assemblies, the members (both elected and nominated) of the state legislative councils (in case of the bicameral legislature) do not participate in the election of the President.

Statement 3 is correct: A candidate, in order to be declared elected to the office of President, must secure a fixed quota of votes. The quota of votes is determined by dividing the total number of valid votes polled by the number of candidates to be elected plus one and adding one to the quotient.
