The correct answer is 2, which is 12 schedules. The schedules in the Indian Constitution are appendices that contain additional laws and provisions. They cover various topics such as the allocation of powers between the central government and the state governments, the languages recognized in India, and the representation of states in the Rajya Sabha (the upper house of Parliament). Each schedule deals with a specific aspect of governance and defines the procedures and rules related to it. It is important to note that the schedules can be amended or repealed by Parliament as per the procedures mentioned in the Constitution.
