Which Indian visa category has been renamed the Visitor Visa?

The correct answer is Tourist Visa. The erstwhile Tourist Visa is now called the Visitor Visa, a change made because the category permits a far wider set of purposes than conventional tourism. It is split into V-1 and V-2. V-1 is granted for 30 days with multiple entries and covers business meetings, medical consultations, wellness retreats, short-duration treatment and short courses in Indian languages, music, art and craft. V-2 is meant for longer visits with validity of 1, 5 or 10 years and additionally covers mountaineering, for which a six-month multiple-entry visa is granted. Option A is wrong because the Business Visa kept its name and was split into B-1 and B-2. Option C is wrong because the Medical Visa also kept its name, with M-1 and M-3 for treatment and M-2 and M-4 for attendants. Option D is wrong because the Miscellaneous Visa is a separate residual category covering persons of Indian origin and other specified purposes.
