One hypothesis suggested to explain the uniform age of the surface of Venus is that
a. Venus' surface is 4 billion years old and has not been affected by flooding or slow evolution.
b. Venus' surface is made of rocks that are much harder than Earth's and thus last longer.
c. Venus periodically goes through a catastrophic melting of the entire surface.
d. Venus' clouds protect it from meteorites so that very few impacts occur to change its surface.
e. dust storms deposit large amount of dust on the surface making it appear of uniform age.
