Match the antibiotics in $\text{Group I}$ wiith the targets in $\text{Group II}$.

$\begin{array}{|l|l|l|l|} \hline & \text{Group I} & & \text{Group II} \\ \hline P. & \text{Sulfonamide} & 1. & \text{Peptidoglycan synthesis} \\ \hline Q. & \text{Quinolones} & 2. & \text{Peptide chain elongation} \\ \hline R. & \text{Erythomycin} &3. & \text{Folic acid biosynthesis} \\ \hline S. & \text{Cephalosporin} & 4. & \text{Topoisomerase} \\ \hline \end{array}$

1. $\text{P-3, Q-4, R-1, S-2}$
2. $\text{P-2, Q-4, R-3, S-1}$
3. $\text{P-4, Q-1, R-2, S-3}$
