Which of the following is a biodegradable polymer?

Match the polymers given in Column-$I$ with their repeating units given in Column-$II$.

Column-$I$	Column-$II$
$A$. Acrilan	$i$. $-[CH_2-CH(CN)]_n-$
$B$. Polystyrene	$ii$. $-[CH_2-CH(C_6H_5)]_n-$
$C$. Neoprene	$iii$. $-[CH_2-C(Cl)=CH-CH_2]_n-$
$D$. Novolac	$iv$. $-[CH_2-CH=CH-CH_2-CH_2-CH(CN)]_n-$
$E$. Buna-$N$	$v$. Linear phenol-formaldehyde polymer

Match List-$I$ (polymer) with List-$II$ (monomer/s) and select the correct option:
| List-$I$ (polymer) | List-$II$ (monomer/s) |
| :--- | :--- |
| $(A)$ Bakelite | $(I)$ $2$-Methyl-$1,3$-butadiene |
| $(B)$ Natural rubber | $(II)$ Glycine + Aminocaproic acid |
| $(C)$ Glyptal | $(III)$ Phenol + formaldehyde |
| $(D)$ Nylon $2$-Nylon $6$ | $(IV)$ Phthalic acid + ethylene glycol |

Match the polymer of column-$I$ with correct monomer of column-$II$.

column-$I$	column-$II$
$A$. High density polythene	$i$. Isoprene
$B$. Neoprene	$ii$. Tetrafluoroethene
$C$. Natural rubber	$iii$. Chloroprene
$D$. Teflon	$iv$. Acrylonitrile
$E$. Acrilan	$v$. Ethene
