D)depends on the density, not the mass of the bodies.
E)depends on the temperature, density, and size of the bodies.

The force of gravity between two objects increases with their masses, but decreases with the square of the distance between them. This is commonly known as the inverse square law. According to Newton's law of universal gravitation, the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that as the masses of the objects increase, so does the force of gravity, but as the distance between them increases, the force of gravity decreases rapidly (as the square of the distance). Choice B is the only option that reflects this relationship.
