Comparing the electrostatic force and the gravitational force we can say that
A. both have the same dependence on distance, the electrostatic force can be either attractive or repulsive while the gravitational force is only attractive, and the electrostatic force is stronger.
B. the electrostatic force falls off more rapidly with distance, the electrostatic force can be either attractive or repulsive while gravitation is only attractive, and the electrostatic force is stronger.
C. both have the same dependence on distance, both involve attraction and repulsion, but the gravitational force is stronger.
D. both have the same dependence on distance, the electrostatic force can be either attractive or repulsive while the gravitational force is only repulsive, and the electrostatic force is weaker.
E. both have the same dependence on distance, both involve attraction and repulsion, but the electrostatic force is stronger.
