Answer:
A
Step-by-step explanation:
Gravity and mass are directly related as a law of the universe. The bigger the mass of an object the higher the gravitational pull it has. Smaller objects will, therefore, be pulled towards the bigger objects. Part of the reason also is that bigger object have more inertia than smaller objects. Even though the smaller object may have some gravitational pull on the larger object, the lower inertia of the smaller object will cause it to be pulled and accelerate more towards the larger object than vice versa.
