Concept:Article 63 of the Indian Constitution specifically creates and defines the office of the Vice-President of India.Explanation:The Constitution states in Article 63 that “There shall be a Vice-President of India.” This makes the Vice-President a separate constitutional office. The Vice-President also serves as the ex-officio Chairman of the Rajya Sabha. In case the President is absent, resigns, is impeached, or dies, the Vice-President acts as the President. Article 66 then explains the election procedure for the Vice-President. Other offices are set up by different articles: the President under Article 52, the Prime Minister under Article 74, and the Governor under Article 153. Thus, Article 63 directly refers only to the Vice-President.Answer:A. Vice-President
