Answer to Question 1

C

Answer to Question 2

All small meteoroids burn up in the thick atmosphere. Only large ones reach the surface. Thus, there are no small impact craters, only large ones. Also, the heavy volcanic activity continuously changes the surface, covering up older impact craters, so that there are few impact craters compared to the Moon or Mercury.
