The correct answer is option 2: President. The Chief Election Commissioner of India is appointed by the President of India. This appointment is made under the provisions of Article 324 of the Constitution of India. The Chief Election Commissioner is the head of the Election Commission of India, which is an independent constitutional authority responsible for conducting elections in the country. It is important to note that the Chief Election Commissioner is appointed by the President, and not by any other authority such as the Chief Justice of India, Parliament, or the Prime Minister.
