Mercury is always much closer to the Sun than Venus is, and yet it never appears brighter than Venus, even when at maximum brightness.  Why is this?
A)   We never see more than a small fraction of Mercury's illuminated surface because of its orbital path relative to that of the Earth; hence, it always appears dark.
B)   Because Mercury has a thick atmosphere that impedes reflection from its surface, making it appear dark
C)   Because Mercury has a high albedo, or reflectivity, but is very small and hence appears relatively dark
D)   Because Mercury is small, has a dark surface, and has no reflecting clouds
