Solution
The correct option is C liquid hydrogen + liquid oxygen
The primary performance advantage of liquid propellants is due to the oxidizer. Several practical liquid oxidizers (liquid oxygen, nitrogen tetraoxide, and hydrogen peroxide) are available which have better specific impulse than the ammonium perchlorate used in most solid rockets, when paired with comparable fuels.
Liquid hydrogen and liquid oxygen are used as propellent for rocket.
