The concurrent list in the Indian Constitution is adopted from the Constitution of Australia. The concurrent list is a part of the Indian federal system and includes subjects on which both the central government and the state governments have the power to make laws. The idea of having a concurrent list was borrowed from Australia, where they also have a similar division of powers between the federal government and the state governments. The concurrent list allows for a shared responsibility between the central and state governments, ensuring a balance of power and decentralization of authority. It is important to note that while the answer provided is generally correct, it is ultimately the adoption from the Constitution of Australia and not any other country mentioned in the options.
