Chemistry Question on classification of polymers

The monomer of PMMA is:

A

CH2       ‾‾ CHCNC{{H}_{2}}\overline{\overline{\,\,\,\,\,\,\,}}\,CHCN

B

CF2       ‾‾ CF2C{{F}_{2}}\overline{\overline{\,\,\,\,\,\,\,}}\,C{{F}_{2}}

C

CH2       ‾‾ C∣ CH3       ‾COOCH3C{{H}_{2}}\overline{\overline{\,\,\,\,\,\,\,}}\,\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,\overline{\,\,\,\,\,\,}COOC{{H}_{3}}

D

methyl meth-acetate

Answer

CH2       ‾‾ C∣ CH3       ‾COOCH3C{{H}_{2}}\overline{\overline{\,\,\,\,\,\,\,}}\,\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,\overline{\,\,\,\,\,\,}COOC{{H}_{3}}

Explanation

Solution

PMMA is the polymer of methyl methacrylate. It is used in making gaskets, valves, seals etc.
