2. 1, 2 and 4 only
3. 1 and 2 only
4. 2, 3 and 4 only

Answer (Detailed Solution Below)

Option 3: 1 and 2 only

Detailed Solution

Answer. The correct answer is 1 and 2 only.

The Indian Standard Meridian establishes Indian Standard Time (IST), which is exactly UTC+5:30. Besides Uttar Pradesh and Andhra Pradesh, this longitude traverses three other states: Madhya Pradesh, Chhattisgarh, and Odisha.

India follows Indian Standard Time (IST) as its only official time zone. IST is calculated at UTC +5:30, based on the mean solar time at the 82.5°E longitude line passing through Mirzapur (near Allahabad) in Uttar Pradesh. This system was formalized during the British colonial era to unify the time system across the country and simplify administration, transportation, and communication. There is only one time zone in India.
