Vedclass · Answer

(C) The $PSLV$ (Polar Satellite Launch Vehicle) is a multi-stage rocket. It utilizes a combination of solid and liquid propellants in its different stages. Specifically,it uses composite solid propellants in the booster stages and liquid propellants (like $N_2O_4$ with $UDMH$ or $MMH$) in the liquid stages to achieve the required thrust and control. Therefore,both $(A)$ and $(B)$ are used in different stages of the rocket.
