Explanation:

Indian Constitution is the living, mixed, longest, written Constitution applicable for Union and all states. In the written constitution like the US Constitution, it is very difficult to make amendments. The US Constitution, therefore, is a rigid constitution. However, the Indian Constitution is neither as flexible as the British Constitution nor as rigid as the US Constitution. It reflects the value of continuity and change. Therefore tt is neither too rigid nor too flexible in nature. Hence option 2nd is correct.
