The correct answer is option 4: "Not a member of the Parliament." The Vice-President of India is not a member of either the Lok Sabha or the Rajya Sabha. Unlike the President, who is the head of state and also a member of the Parliament, the Vice-President`s role is primarily ceremonial and advisory in nature. The Vice-President is elected by an electoral college consisting of members of both houses of Parliament, and the individual holding this office presides over the Rajya Sabha. However, the Vice-President does not have voting rights in the event of a tie in the Rajya Sabha, and cannot be a member of any political party while holding this position.
