Match the following :
\(\begin{array}{llll} \hline & \text { List I } & & \text { List II } \\ \hline \text { (A) } & \text { Teflon } & \text { I. } & \mathrm{SnCl}_2 \\ \hline \text { (B) } & \text { Anionic polymerisation } & \text { II. } & \mathrm{C}_2 \mathrm{~F}_1 \\ \hline \text { (C) } & \text { Cationic polymerisation } & \text { III. } & \text { Bakelite } \\ \hline \text { (D) } & \text { Thermosetting polymer } & \text { IV. } & \text { Polystyrene } \\ \hline & & \text { V. } & \text { RLi } \\ \hline \end{array}\)
The correct answer is

1. A \(\begin{array}{ccccc} \text { A } & \text { B } & \text { C } & \text { D } \\ \text { II } & \text { I } & \text { V } & \text { III } \end{array}\)
2. B \(\begin{array}{ccccc} \text { A } & \text { B } & \text { C } & \text { D } \\ \text { II } & \text { V } & \text { I } & \text { IV } \end{array}\)
3. C \(\begin{array}{ccccc} \text { A } & \text { B } & \text { C } & \text { D } \\ \text { II } & \text { V } & \text { I } & \text { III } \end{array}\)
4. D \(\begin{array}{ccccc} \text { A } & \text { B } & \text { C } & \text { D } \\ \text { V } & \text { II } & \text { I } & \text { IV } \end{array}\)
