Solution:
The Constitution of India divided the powers between the centre and states into 3 lists. These lists are Union List, State List, and Concurrent List.
The Union List includes the subjects which hold national importance, and a uniform policy is needed throughout the country. Subjects of the Union List are communications, banking, currency, foreign affairs, etc.The State List includes subjects that carry importance for states and local administration, such as agriculture, irrigation, police, etc. The Concurrent List comprises the subjects holding the union as well as the states' interests. The laws on such subjects, e.g., education, forests, etc., can be made by both the union as well as the state governments.
