Arocket can fly into space because ?

a. when it is launched, the hot exhaust gases hit the ground and push the rocket forward.

b. the rocket pushes the exhaust gases backward, and there is an equal and opposite reaction pushing the rocket forward.

c. when the gases are burning up, the mass of the rocket decreases, changing the amount of gravity on the rocket.

d. the launch pad pushes the rocket forward like a slingshot.

The rocket pushes the exhaust gases backward and there is an "equal and opposite reaction" that pushes the rocket forward.

Option (b)

Explanation:

Rocket is one of the propulsive unit functions similar to air-filled balloons and it works on the principle of newton thirds law of motion.

This law states that for every action there will be an equal and opposite reaction.

The fuel is burned inside the rocket and it releases the exhaust gas and these gases create an impact of force that propels the rocket into space.
