The correct answer is option 4, President. The Finance Commission is a constitutional body that is responsible for the distribution of financial resources between the central government and the state governments in India. It is appointed by the President of India. The Finance Commission consists of a Chairman and four other members who are chosen by the President. It is important to note that the Finance Minister, Prime Minister, and Speaker of the Lok Sabha do not have the authority to directly appoint members to the Finance Commission. Therefore, the correct answer is option 4.
