Match the entries in $\text{Group I}$ with the enzymes in $\text{Group II}$.

$\begin{array}{|l|l|l|l|} \hline & \text{Group I} && \text{Group II} \\ \hline P. & \text{NAD}^+ & 1. & \text{Glutathione peroxidase} \\ \hline Q. & \text{Selenium} & 2. & \text{Nitrogenase} \\ \hline R. & \text{Pyridoxal phosphate} & 3. & \text{Lactate dehydrogenase} \\ \hline S. & \text{Molybdenum} & 4. & \text{Glycogen phosphorylase} \\ \hline \end{array}$

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