SLV-3 rockets use
A) Solid propellants
B) Liquid propellants
C) hybrid propellants
D) composite solid propellants
E) none of the above

Hint: Rocket fuel is commonly called as a propellant. It is the reaction mass of the rocket. It is called so because it is ejected at the possible highest velocity so as to push the rocket upwards or to receive the maximum thrust to overcome the force of gravity.

Complete step by step answer:
The name propellant itself denotes that its duty is to provide the required thrust to push the machine or body upwards. We know that the force of gravity employed by the earth keeps all substances on earth. If any object wants to overcome it, it needs to overcome this force. We can see propellants used in vessels moving in water bodies. They always contain a rotating blade connected to a motor which pushes the vessel through the water body
Likewise, rockets also use propellants to gain the thrust so as to push the vehicle upwards and to overcome the gravitational force and the force of gravity. It is the simple application of Newton's third law of motion.
SLV-rockets are Satellite Launch Vehicles which are used to carry various satellites meant for different research purposes in space missions. Most satellite launch vehicles use solid propellants and they are a four-stage rocket, that is, parts of it get detached at various stages in its propagation and only the part carrying the satellite reaches the final stage or at the planet at where it is meant to be reached. SLV-3 is a highly efficient rocket and it uses composite solid propellants which are a mixture of polymeric binders and ammonium perchlorate as an oxidiser.

So, the correct answer is Option C .

Additional Information:
Rockets use propellants to obtain the thrust to overcome the force of gravity. It is the simple application of Newton's third law of motion, that is, for every action there will be an equal and opposite reaction.

Note: SLVs are satellite launch vehicles or simply rockets used to carry satellites to their desired target planets or something and we use mass called propellants as fuel in it to obtain the required thrust to push up the vehicle to make it move.
