Match materials given in Column-$I$ with the polymers given in Column-$II$.

Column-$I$	Column-$II$
$A$. Natural rubber latex	$i$. Nylon
$B$. Wood laminates	$ii$. Neoprene
$C$. Ropes and fibres	$iii$. Dacron
$D$. Polyester fabric	$iv$. Melamine formaldehyde resins
$E$. Synthetic rubber	$v$. Urea-formaldehyde resins
$F$. Unbreakable crockery	$vi$. cis-polyisoprene

(A-VI, B-V, C-I, D-III, E-II, F-IV) The correct matches are as follows:
$A$ (Natural rubber latex) $\rightarrow$ $vi$ (cis-polyisoprene)
$B$ (Wood laminates) $\rightarrow$ $v$ (Urea-formaldehyde resins)
$C$ (Ropes and fibres) $\rightarrow$ $i$ (Nylon)
$D$ (Polyester fabric) $\rightarrow$ $iii$ (Dacron)
$E$ (Synthetic rubber) $\rightarrow$ $ii$ (Neoprene)
$F$ (Unbreakable crockery) $\rightarrow$ $iv$ (Melamine formaldehyde resins)
Therefore,the correct sequence is: $A-vi, B-v, C-i, D-iii, E-ii, F-iv$.
