The combination that correctly matches the polymer in Group-$1$ with the polymerization reaction type in Group-$2$ is

$\begin{array}{cc}\ &\text{Group-1} & \text{Group-2} \\ &\text{P. Nylon 6} & \text {I. Condensation polymerization} \\ &\text{Q. Polypropylene} & \text{II. Ring opening polymerization} \\ &\text{R. Polyester} & \text{III. Addition polymerization } \\ \\ \end{array}$

1. $P-II$, $Q-I$, $R-III$
2. $P-I$, $Q-III$, $R-II$
3. $P-III$, $Q-II$, $R-I$
4. $P-II$, $Q-III$, $R-I$
