The correct answer is option 1: India is 5 hours ahead of GMT. GMT, or Greenwich Mean Time, is the time at the Prime Meridian, which is located in Greenwich, London. India, being located in the UTC+5:30 time zone, is 5 hours ahead of GMT during standard time. This means that when it is 12:00 PM (noon) in Greenwich, it is 5:30 PM in India. It`s important to note that India follows Indian Standard Time (IST) throughout the year and does not observe daylight saving time. Therefore, the time difference between India and GMT remains constant.
