We can calculate the distance ratio between the Sun and the Moon by dividing the time it takes for light to travel from each object to Earth. 
For the Moon, we have: distance = speed x time = 299,792,458 m/s x 1.3 s = 389,242 km
For the Sun, we have: distance = speed x time = 299,792,458 m/s x 8 minutes x 60 seconds/minute = 143,600,000 km
So the distance ratio is: 143,600,000 km / 389,242 km = 368.7
This means that the Sun is about 370 times farther from the Earth than the Moon. Therefore, the answer is D.
