The correct option is D The Union list
The Indian Constitution, like many others, actually has both unitary and federal features. Both the Central and State legislatures have the power to make laws, but the subjects of legislation differ. The constitution has laid out three lists to demarcate these subjects: the Union list, the State list, and the Concurrent list. The Union list has 100 subjects, the State list initially consisted of 61 subjects, and the Concurrent list has 52 subjects.
