Newton was the first to perform the experiment of a beam of sunlight travelling through a prism. If you hunt this down on the internet, you will find that the whole spectrum of visible light is in a ray coming from the sun. The diagram below shows what he did. Sorry! I can't get the diagram to upload.
So the answer has to be B.

You have to translate 180 days to seconds.
180 days [24/1 day] [3600 sec/1 hour] = 15552000 second
d = r*t
d = ?
r= 3*10^8 m/s
t = 15552000 second
d = 3*10^8 * 15552000
d = 467 * 10^15 meters which is D
