hi I did not understand your question the question maybe not like that
is the question Is this What is the longitude of a place where the local time is 4pm when the GMT is 12 noon?
the answer will be this ok....
The difference in longitudes will be 112.5° (450/4). Since the time at given place is less than GMT, the place is to the west of GMT. So, the longitude of a place where the local time is noon is 112.5° W
It's a really hard choice between A or D I would go with D because it seems to make more sense. Then again A Is a really good one just go with D if not then D. :)
