Correct Answer: Option D
Explanation

Synthetic rubber produced by the polymerization of chlorobutadiene (specifically 2-chloro-1,3-butadiene, also known as chloroprene) is called neoprene. This polymer, also known as polychloroprene, is valued for its chemical stability and flexibility across a wide temperature range. While modern commercial production often uses emulsion polymerization, historical and theoretical contexts (like those found in certain chemistry examinations) link this specific monomer to the formation of neoprene.
