Correct option: D

${\text{C}}{{\text{H}}_{\text{2}}}{\text{ = }}\mathop {\text{C}}\limits_{\begin{array}{cccccccccccccccccccc} {\text{|}} \\ {{\text{Cl}}} \end{array}} {\text{ - CH = C}}{{\text{H}}_{\text{2}}}$

Option D (${\text{C}}{{\text{H}}_{\text{2}}}{\text{ = }}\mathop {\text{C}}\limits_{\begin{array}{cccccccccccccccccccc} {\text{|}} \\ {{\text{Cl}}} \end{array}} {\text{ - CH = C}}{{\text{H}}_{\text{2}}}$) is correct because chloroprene is the monomer of neoprene.
