Q: A solar eclipse takes place such with numerous observers on Earth. During such an event, the moon perfectly aligns in front of the sun, thus eclipsing the sun and casting the Earth into darkness. A halo may form around the the eclipse which reflects light from the sun passing around the moon. Assuming the moon is a distance X from Earth and the sun is a distance Y from Earth, which of the following expressions reflects the amount of time it takes for light from the halo to reach an observer's eyes? Assume the speed of light is c.
A		X/c
B		Y/c
C		X/2c
D		Y/2c
