Option 1 is correct as per the provisions of the Indian Constitution. The President of India can be impeached by the Indian Parliament for the violation of the Constitution or acts of serious misconduct. Impeachment proceedings can be initiated in either house of Parliament and a resolution must be passed by a majority of the total membership of that house.

Option 2 is not correct. The approval of the Chief Justice of India is not required for the removal of the President of India. The procedure for the removal of the President is outlined in Article 61 of the Indian Constitution. It involves the presentation of a notice of resolution for the President`s removal in either house of Parliament, followed by an investigation and the passing of the resolution by a special majority.

Therefore, the correct answer is option 1.
