Explanation:

The Concurrent List includes subjects that give powers to both the Centre and state governments. Subjects like Education including technical education, medical education and universities, population control and family planning, criminal law, prevention of cruelty to animals, protection of wildlife and animals, forests, electricity, marriage etc. However, given that there can be conflict when it comes to laws passed by Parliament and state legislatures on the same subject, the Constitution provides for a central law to override a state law. Hence option 3rd is correct.
