NEET 2023 Chemistry question on Polymers

Which amongst the following molecules on polymerization produces neoprene?
  1. A.
    H2C=CH−CH=CH2\text{H}_2\text{C}=\text{CH}-\text{CH}=\text{CH}_2
  2. B.
    H2C=C∣(Cl)−CH=CH2\text{H}_2\text{C}=\overset{|}{\underset{}{\text{C}}}(\text{Cl})-\text{CH}=\text{CH}_2
  3. C.
    H2C=CH−C≡CH\text{H}_2\text{C}=\text{CH}-\text{C}\equiv\text{CH}
  4. D.
    H2C=C∣(CH3)−CH=CH2\text{H}_2\text{C}=\overset{|}{\underset{}{\text{C}}}(\text{CH}_3)-\text{CH}=\text{CH}_2
