Answer:
The right choice is (D) A bat hitting a ball
Step-by-step explanation:
In physics, a contact force is a force that acts at the point of contact between two objects. In other word contact force is the force in which an object comes in contact with another object. On the other hand the non-contact force acts on the physically separated objects such as gravitational force or the force between the sun and stars or satellites. SO among the given options, a bat hitting the ball is the example of contact forces.
