Which of the following is not a federal of the Indian Constitution?
Option 3 is the right answer.
Though the Indian Constitution is federal and envisages a dual polity (Centre and states), it provides for only a single citizenship, that is,
the Indian citizenship. In countries like USA, on the other hand, each person is not only a citizen of USA but also a citizen of the particular state to which he belongs. Thus, he owes allegiance to both and enjoys dual sets of rights—one conferred by the National government and another by the state government.
