In the case of a dispute in the election of the President, it can be referred to the Supreme Court of India. The Chief Election Commissioner is responsible for conducting and overseeing elections but does not have the authority to resolve disputes related to the election of the President. The Parliament, on the other hand, is primarily responsible for making laws and governing the country and does not have the jurisdiction to decide on election disputes. Therefore, the correct option is option 3, Supreme Court of India. It is important to note that this answer is generally correct, but in some cases, the dispute may also be referred to the High Court if it involves the election of a state president.
