For the CNC part programming, match Group A with Group B:
$\begin{array}{|l|l|l|l|} \hline & \textbf{Group A} && \textbf{Group B} \\ \hline P: & \text{circular interpolation, counter clock wise} & I: & G02 \\ \hline Q: & \text{dwell} & II: & G03 \\ \hline R: & \text{circular interpolation, clock wise} & III: & G04 \\ \hline S: & \text{point to point countering} & IV: & G00 \\ \hline\end{array}$
- $P-II, Q-III, R-I, S-IV$
- $P-I, Q-III, R-II, S-IV$
- $P-I, Q-IV, R-II, S-III$
- $P-II, Q-I, R-III, S-IV$
