Identify the structure of the polymer 'P' formed in the given reaction

Caprolactam $\xrightarrow[\mathrm{H}_2 \mathrm{O}]{533-543 \mathrm{~K}} P$

The monomer which is present in both bakelite and melamine polymers is

Match the following.

List-I (Monomer/s)	List-II (Name of polymer)
A. CF₂$=$CF₂	I. Neoprene
B. NH₂(CH₂)₆NH₂, HO₂C(CH₂)₄CO₂H	II. Bakelite
C. C₆H₅OH₃ HCHO	III. Teflon
D. CH₂$=$CH(Cl)—CH$=$CH₂	IV. Nylon 6,6

The correct answer is

$$ \text { Match the following. } $$

$$ \begin{array}{llll} \hline & \text { List-I (Polymer type) } & & \text { List-II (Example) } \\ \hline \text { A. } & \text { Fibre } & \text { I. } & \text { Bakelite } \\ \hline \text { B. } & \text { Elastomer } & \text { II. } & \text { Polystyrene } \\ \hline \text { C. } & \text { Thermosetting polymer } & \text { III. } & \text { Neoprene } \\ \hline \text { D. } & \text { Thermosplastic polymer } & \text { IV. } & \text { Dacron } \\ \hline \end{array} $$

The correct answer is
