- Propulsion is the act of moving or pushing an object forward. A propulsion system is an engine that produces thrust to push an object, such as an airplane or rocket, forward.
- The propulsion of all rockets is explained by the same physical principle: Newton’s third law of motion.
- It states that all forces exist in pairs: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal and opposite: FA = −FB.
- A rocket’s acceleration depends on three major factors: the exhaust velocity, the rate the exhaust is ejected, and the mass of the rocket.
- To achieve the high speeds needed to hop continents, obtain orbit, or escape Earth’s gravity altogether, the mass of the rocket other than fuel must be as small as possible.

Option (d) becoz--->
As v know that the principle of rocket propulsion works on the 'Newton's Third Law of Motion'. It states that, 'to every action, there is always an equal and opposite reaction'....so the momentum imparted to the rocket is equal and opposite to that of the gases. Hence their total momentum is zero.
