The earth's gravitational force field is said to be conservative force field because

[A].	The value of gravitational force rise is fixed	[B].	The direction of gravitational force is fixed
[C].	The work acted by the earth's gravitational field on a particle is independent on the path traced out by the particle	[D].	The work acted by the erth's gravitational field will cause same path for all particles irrespective of their mass
[E].	The gravitational field has only single directional component always acting normal to a body

Answer: Option C
