The election of the President is held through single transferable vote system of proportional representation. Under this system names of all the candidates are listed on the ballot paper and the elector gives them numbers according to his/her preference. Every voter may mark on the ballot paper as many preferences as there are candidates. Thus, the elector shall place the candidate 1 opposite the name of the candidate whom he/she chooses for first preference and may mark as many preferences as he/she wishes by putting the candidate 2, 3, 4 and so on against the names of other candidates. The ballot becomes invalid if first preference is marked against more than one candidate or if the first preference is not marked at all.

Hence, option (B) is correct.

Disqualification

The question of disqualification under the Tenth Schedule is decided by the Chairman in the case of Rajya Sabha and Speaker in the case of Lok Sabha (and not by the president of India).

In 1992, the Supreme Court ruled that the decision of the Chairman/Speaker in this regard is subject to judicial review.

However, when the disqualification is subject to the criteria laid down in the Constitution and the Representation of People Act (1951), the President's decision is final. In such a case, he should obtain the opinion of the election commission and act accordingly.

* The Vice President of India:

* The Vice-President occupies the second-highest office in the country which is next to President and also acts as the ex-officio Chairman of Rajya Sabha; and can acts as President when a vacancy occurs in the office of the President due to his resignation, impeachment, death or otherwise.

* The Vice-President, like the President, is elected not directly by the people but by the method of indirect election. He is elected by the members of an electoral college consisting of the members of both Houses of Parliament, i.e. Lok Sabha and Rajya Sabha and members of State legislatures are not part of the electoral college.

* He can be removed by a resolution passed by a majority of all the then members of the Rajya Sabha and agreed to by the Lok Sabha with simple majority (Article 67(b)). But, no such resolution may be moved unless at least 14 days' advance notice has been given.

* The Constitution does not list grounds for removal. No Vice President has ever faced removal or the deputy chairman in the Rajya Sabha cannot be challenged in the court of law per Article 122.

Article 61 in the Constitution of India deals with the Procedure for impeachment of the President. Under Article 67 (b), a Vice President may be removed from his office by a resolution of the council of States passed by a majority of all the then members of the council and agreed to by the House of the People; but no resolution for the purpose of this clause shall be moved unless at least fourteen days notice has been given of the intention to move the resolution. Article 94 deals with the Vacation and resignation of, and removal from, the offices of Speaker and Deputy Speaker. Article 90 Constitution of India deals with the Vacation and resignation of, and removal from, the office of Deputy Chairman.

Term of President’s Office:

The President holds office for a term of five years from the date on which he enters upon his office. However, he can resign from his office at any time by addressing the resignation letter to the Vice President.

Further, he can also be removed from the office before completion of his term by the process of impeachment. The President can hold office beyond his term of five years until his successor assumes charge.

He is also eligible for re-election to that office. He may be elected for any number of terms. However, in USA, a person cannot be elected to the office of the President more than twice.
