Why the answer is B, and why the others tempt you.
The total angular difference between 75°E and 15°W is 75 + 15 = 90°. Since the Earth rotates 15° per hour, the time difference is 90 ÷ 15 = 6 hours. The town at 15°W is west of 75°E, so it is 6 hours behind, giving 12:00 − 6:00 = 06:00 hours. Wait — recalculating: 12:00 noon minus 6 hours = 06:00 hours.
