Solution

The correct option is A Gravitational force
The motion of the earth around the sun is due to gravitation attraction between the two. Also sun is a big celestial objects which exerts large amount of gravitational force that binds the solar system together and is thus responsible for the revolution of planets around the sun. Hence motion of earth around the sun is due to gravitational force.
