Planet a Has Twice the Mass of Planet B

Multiple Choice

Planet A has twice the mass of Planet B.From this information,what can we conclude about the acceleration due to gravity at the surface of Planet A compared to that at the surface of Planet B?

A) The acceleration due to gravity on Planet A must be twice as great as the acceleration due to gravity on Planet B.
B) The acceleration due to gravity on Planet A must be four times as great as the acceleration due to gravity on Planet B.
C) The acceleration due to gravity on Planet A is the same as the acceleration due to gravity on Planet B.
D) The acceleration due to gravity on Planet A is greater than the acceleration due to gravity on Planet B,but we cannot say how much greater.
E) We cannot conclude anything about the acceleration due to gravity on Planet A without knowing the radii of the two planets.
