1) Newton’s Third Law
2) Principle of Conservation of Momentum
Here’s the detailed explanation:
Newton's Third Law of Motion and Rocket Propulsion:
• Newton's Third Law of Motion: 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'.
• Application: In the case of a rocket, the engine emits hot burning gases in the downward direction. These gases apply an equal and opposite reaction force to the rocket in the upward direction.
Principle of conservation of momentum and Rocket Propulsion:
• The principle of conservation of momentum: It states that whenever two bodies collide or get separated, then their total momentum before collision or separation is equal to their total momentum after collision or separation.
• Application: Since the gases of the rocket and the rocket are stationery at the start, their total momentum is zero. After the gases start burning, the momentum imparted to the rocket is equal and opposite to that of the gases. Hence their total momentum is zero.
Hence, Correct Answer is B

Principle Followed in Rocket Take Off
The principle followed in the take off of a rocket is the conservation of momentum.
Explanation
Conservation of momentum is a fundamental law of physics that states that the total momentum of a system of objects remains constant if no external forces act on the system. In the case of a rocket, the large volume of gases produced by the combustion of fuel is allowed to escape through its tail nozzle in the downward direction with tremendous speed. As per the conservation of momentum principle, for every action, there is an equal and opposite reaction. Hence, when the gases are expelled downwards with a high velocity, the rocket experiences an equal and opposite force, propelling it upwards.
This principle is based on Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In this case, the action is the expulsion of gases downwards, and the reaction is the upward propulsion of the rocket.
Conclusion
Thus, it can be concluded that the take off of a rocket is based on the principle of conservation of momentum, which states that the total momentum of a system remains constant if no external forces act on the system. The rocket expels gases downwards with a high velocity, and the equal and opposite reaction propels it upwards.
The principle followed in the take off of a rocket is the conservation of momentum.

Law of conservation of momentum states that For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied.
Therefore, momentum can neither be created nor destroyed. Law of conservation of momentum is an important consequence of Newton’s third law of motion. Following are the examples of law of conservation of momentum:
1. Air filled balloons
2. System of gun and bullet
3. Motion of rockets
