Verified Answer :

a bowling ball has the most gravitational force.

Answer:

A bowling ball        

Explanation:

We know that the gravitational force acting on an object is given by:

\(F=\dfrac{Gm_1m_2}{r^2}\)

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).
