The correct answer is A) 6:30 A.M.
New Delhi, India observes Indian Standard Time (IST), which is UTC+5:30. London, UK primarily observes Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC), which is UTC+0. During parts of the year, the UK observes British Summer Time (BST), which is UTC+1. Assuming the question refers to the standard time difference (UTC vs UTC+5:30), New Delhi is 5 hours and 30 minutes ahead of London. To find the time in London, subtract 5 hours and 30 minutes from the time in New Delhi. If it is 12:00 noon in New Delhi, subtracting 5 hours gives 07:00, and subtracting another 30 minutes gives 06:30.
The calculation is: 12:00 (New Delhi time) – 5 hours 30 minutes (time difference) = 06:30. Since 12 noon is in the middle of the day, 06:30 will be in the morning. Therefore, it is 6:30 A.M. in London.
