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

(A-V, B-III, C-I, D-II, E-IV) The correct matches are as follows:
$A$. High density polythene is formed from $v$. Ethene.
$B$. Neoprene is formed from $iii$. Chloroprene.
$C$. Natural rubber is formed from $i$. Isoprene.
$D$. Teflon is formed from $ii$. Tetrafluoroethene.
$E$. Acrilan is formed from $iv$. Acrylonitrile.
Thus,the correct sequence is $A-v, B-iii, C-i, D-ii, E-iv$.
