Concept:Longitudes east of the Greenwich Meridian see the Sun earlier, so their local time is ahead of Greenwich Mean Time.Explanation:The Greenwich Meridian is at $0^\circ$ longitude.The given place is at $60^\circ$E.So, the longitude difference is $60^\circ$.Every $15^\circ$ of longitude equals a time difference of $1$ hour.For $60^\circ$, the total time difference is:$$60^\circ \times \frac{1 \text{ hour}}{15^\circ} = 4 \text{ hours}$$Since the place is at $60^\circ$E, it is ahead of Greenwich.Thus, Greenwich time is behind this place.We subtract the time difference from the given local time.$$12:00 \text{ noon} - 4 \text{ hours} = 8:00 \text{ a.m.}$$Answer:The time at Greenwich Meridian is $8:00$ a.m.Correct option: C. $8.00$ a.m.
