Answer:
A) It is possible using the rockets
Explanation:
Spaceships don't have propellers, those require a fluid medium to work, and there is none in the vacuum of space.
Rocket thrusters do not require any fluid medium or being surrounded by any gas to work. Rockets work by the principle of conservation of momentum, they expell some propellant mass backwards at a high speed. In order to conserve momentum in the rocket-propellant system, the rocket increses it's speed forwars.
