Poly(styrene) is an addition polymer. The partial structure of poly(styrene) is shown. [structure: -C(H)(C6H5)-C(H)(H)- repeating unit] What is the formula of the monomer from which poly(styrene) is made?

1. AH-C(H)(C6H5)-C(H)(H)-H
2. BH-C(H)=C(C6H5)-H
3. CH-C(H)(C6H5)-C(H)(H)-C(H)(C6H5)-H
4. DC6H5-C(H)=C(H)-C6H5
