How can you launch a rocket into space from the surface of the Earth if gravity always exerts a force pulling the rocket down?

How can you launch a rocket into space from the surface of the Earth if gravity always exerts a force pulling the rocket down?

A.     The acceleration of system is still equal to g even though it goes into space

B.     Gravity does not matter in space, and therefore you do not have to account for its acceleration when launching a rocket

C.     Newtons second law does not hold for a non-inertial reference frame

D.     The propulsion of the rocket exerts a force greater than the force of gravity
