Answer:
Gravitational force decreases as the masses of 2 objects decreases and the distance between them increases.
Step-by-step explanation:
The force of gravity is the force that depends on the masses and distance between them. The force of gravity is given by :

Here,
G is the universal gravitational constant
d is the distance between masses
It is clear that the Gravitational force decreases as the masses of 2 objects decreases and the distance between them increases. So, the correct option is (d).
