Answer:
A bowling ball
Step-by-step explanation:
We know that the gravitational force acting on an object is given by:

Where
r is the distance between two masses
Also the force of gravity is equal to the weight of an object. It is given by:
W = mg
g is the acceleration due to gravity that varies with location.
It is clear that the gravitational force depends on the mass of an object. Out of given options a bowling ball has maximum mass. So, it will possess maximum gravitational force. Hence, the correct option is (c).
