Answer to Question 1

D

Answer to Question 2

Venus has a thick cloud cover that prevents us from seeing the surface with visible light. Radar can map the surface, but its longer wavelength means the resolution is worse. Mars' atmosphere is thin enough that we can see surface detail from Earth. Also, we have landed several spacecraft on Mars, some of which have traveled over the surface. The few spacecraft that made successful soft landings on Venus were very short lived.
