Answer 1

Answer: (B), (C), (D)

A man doing push-ups.

A push or a pull which changes the speed, direction or shape of an object is called Force.
The Sun exerts gravitational force on the Earth due to which the Earth revolves around the Sun.
In the case of a girl shaping a clay doll, force is being exerted on the clay doll such that the shape changes.
A man doing push-ups is exerting muscular force to lift himself up and move down.
A boy looking the television is not feeling a significant force by the television when looking at it.
