Which one of the following statements is correct as per the Constitution of India?

The correct option is "Inter-State quarantine is a Union subject under the Union List."

To understand why this statement is correct, we can examine the Seventh Schedule of the Constitution of India, which divides legislative powers between the Union and the States into three lists: the Union List (List I), the State List (List II), and the Concurrent List (List III).

Let's analyze each of the options provided in the question:
1. Inter-State trade and commerce: According to Entry 42 of the Union List (List I), "Inter-State trade and commerce" falls under the exclusive jurisdiction of the Parliament (Union government), not the State List. Therefore, the first statement is incorrect.
2. Inter-State migration: According to Entry 81 of the Union List (List I), "Inter-State migration; inter-State quarantine" are Union subjects. Since inter-state migration is under the Union List, the second statement is incorrect.
3. Inter-State quarantine: As per Entry 81 of the Union List (List I), "inter-State quarantine" is explicitly listed as a subject under the jurisdiction of the Union government. Thus, this statement is correct.
4. Corporation tax: According to Entry 85 of the Union List (List I), "Corporation tax" is levied and collected by the Union government. It is a Union subject, not a State subject, making the fourth statement incorrect.

Consequently, the only legally accurate statement under the constitutional framework of India is that inter-State quarantine is a Union subject under the Union List.
