The combination that correctly matches the polymer in Group-$1$ with the polymerization reaction type in Group-$2$ is
$\begin{array}{cc}\
&\text{Group-1} & \text{Group-2} \\
&\text{P. Nylon 6} & \text {I. Condensation polymerization} \\
&\text{Q. Polypropylene} & \text{II. Ring opening polymerization} \\
&\text{R. Polyester} & \text{III. Addition polymerization } \\
\\ \end{array}$
- $P-II$, $Q-I$, $R-III$
- $P-I$, $Q-III$, $R-II$
- $P-III$, $Q-II$, $R-I$
- $P-II$, $Q-III$, $R-I$
