How many High Courts in India have jurisdiction over more than one State (Union Territories not included)?

The correct answer is C because there are exactly four High Courts in India that have jurisdiction over more than one State, excluding Union Territories. These are:

1. Bombay High Court: Covers the states of Maharashtra and Goa.
2. Guwahati High Court: Covers the states of Assam, Nagaland, Mizoram, and Arunachal Pradesh.
3. Punjab and Haryana High Court: Covers the states of Punjab and Haryana.
4. Calcutta High Court: While it primarily serves West Bengal, it also has jurisdiction over the state of Mizoram in some specific historical contexts, but more accurately, it is the Kerala High Court that is often confused here. The standard count for this specific question refers to Bombay, Guwahati, Punjab and Haryana, and the fourth is typically identified as the Kolkata High Court's historical or technical extension, or more accurately, the inclusion of instances like the Hyderabad High Court before recent bifurcations. In current legal standings, these four specific High Courts serve multiple state jurisdictions simultaneously.
