Answer: Both 1 & 2
Notes: India located east of Greenwich at 82°30'E is 5 hours and 30 minutes ahead of GMT. So, it is 7:30 p.m. in India when it is 2:00 p.m. noon in London. Some countries have a great longitudinal extent and so they have adopted more than one standard time. For example, in Russia, there are as many as eleven standard times. The earth has been divided into twenty-four time zones of one hour each. Each zone thus covers 15° of longitude. Note: Both Russia and USA have 11 time zones each.  Both India and China have 1 time zone each.
