Key Points

Greenwich Mean Time

It is the time displayed by the Shepherd Gate Clock at the Royal Observatory in Greenwich, London. When the sun is at its highest point exactly above the Prime Meridian, it is noon at Greenwich.
It is not affected by Daylight Saving Time (DST) clock changes.
The Greenwich Meridian (Prime Meridian or Longitude Zero degrees) is the reference point for every Time Zone in the world.
Every 15° longitude represents one hour's difference in time: (24 x 15 = 360, the degrees of a circle).
You can work out the time at every location on earth if you know how many degrees it is east or west of Greenwich.
Greenwich Mean Time of Bhutan is 6 hours and 0 minutes ahead. Hence, Option 4 is correct.

The Indian Government has accepted the meridian of 82.5° east for the standard time which is 5 hours 30 mins, ahead of Greenwich Mean Time.
Greenwich Mean Time of Nepal is 5 hours and 45 minutes ahead.
Greenwich Mean Time of Srilanka is the same as India is 5 hours and 30 minutes ahead.
