Match the classes of RNA molecules in $\text{Group I}$ with their functions in $\text{Group II}$.

$\begin{array}{|l|l|l|l|} \hline & \text{Group I} && \text{Group II} \\ \hline P. & \text{snoRNA} & 1. & \text{Protects germline from transposable elements} \\ \hline Q. & \text{piRNA} & 2. & \text{Blocks translation of selected mRNA} \\ \hline R. & \text{miRNA} & 3. & \text{Template for telomere elongation} \\ \hline S. & \text{snRNA} & 4. & \text{Modification and processing of rRNA} \\ \hline && 5. & \text{Splicing of RNA transcripts} \\ \hline \end{array}$

1. $\text{P-3, Q-5, R-2, S-4}$
2. $\text{P-1, Q-3, R-2, S-5}$
3. $\text{P-1, Q-4, R-5, S-2}$
4. $\text{P-4, Q-1, R-2, S-5}$
