Match the polymerization precesses in Group-$1$ with the polymers in Group-$2$.
$\begin{array}{cc}\
&\text{Group-1} & \text{Group-2} \\
&\text{P. Free radical polymerization} & \text{ I. Nylon 6.6} \\
&\text{ Q. Ziegler Natta polymerization} & \text{II. Polypropylene} \\
&\text{R. Condensation polymerization} & \text{III. Poly vinyl chloride} \\
\\ \end{array}$
Choose the correct set of combination.
