Consider the refinery processes in $\textbf{Group-I}$ and the catalysts in $\textbf{Group-2}$.
$\begin{array}{llll} & \textbf{Group-I} && \textbf{Group-2} \\ \textbf{P} & \text{Hydrodesulfurization} & \textbf{I} & \text{Zeolites} \\ \textbf{Q} & \text{Fluid catalytic cracking (FCC)} & \textbf{II} & Pt/Al_2O_3 \\ \textbf{R} & \text{Naphtha reforming} & \textbf{III} & Co-Mo/Al_2O_3 \\ \end{array}$
The correct combination is
- $P-II, Q-I, R-III$
- $P-III, Q-II, R-I$
- $P-III, Q-I, R-II$
- $P-I, Q-III, R-II$
