Answer : 1. "Vice president"
Explanation :

The Vice president is not appointed by the President. The Vice-President is elected by an electoral college consisting of members of both Houses of Parliament. Vice president is elected by means of the single transferable vote and the voting in such election is by secret ballot. Article 63 to Article 71 of the Indian constitution deals with the Vice-President of India. The Vice-President occupies the second-highest office in the country. He is accorded a rank next to the President in the official warrant of precedence. He is the ex-officio chairman of Rajya Sabha. "The Vice-President is elected for a term of five years" is the correct statement regarding the Vice-President of India. The Vice-President of India is India's second-highest constitutional office after the President. Article 63 of the Indian Constitution provides that 'there shall be a Vice-President of India.' The Vice-President shall act as President in the absence of the President on the grounds of death, resignation, defamation, or other circumstances. The Vice President of India is also the ex officio Chairman of the Rajya Sabha. The current Vice-President of India is Jagdeep Dhankhar. The first vice president of India was Sarvepalli Radhakrishnan.
