Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. It exhibits good chemical stability and maintains flexibility over a wide temperature range.

Neoprene can be further hardened by heating in the presence of sulphur. It contains allylic double bonds which help in introducing sulphur bridges between different polymer chains.

The reason is the correct explanation for the assertion.
