Statement - I In cross linked polymer strong covalent bonds are observed between various linear polymer chains.
Statement II : `Cl-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(Si)-Cl` on hydrolysis gives `OH-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(Si)-OH` and on slight heating it forms condensation polymer. (silicones)
Statement III : All linear polymers are elastomers.
Statement IV : Chloroprene on heating in the presence of very small amounts of oxygen gives polymer of neoprene.
The correct statement is/are

A

I, II, IV only

B

I, III, IV only
