The diagram shows the repeat unit of a polymer. [structure: repeat unit with backbone C-C, H on first C, H and CH2-CH3 on second C] Which row correctly identifies the monomer and type of polymerisation involved in making this polymer?

1. Amonomer: CH2=CH(C2H5); type of polymerisation: addition
2. Bmonomer: CH2=CH(C2H5); type of polymerisation: condensation
3. Cmonomer: CH3-CH=CH-CH3; type of polymerisation: addition
4. Dmonomer: CH3-CH=CH-CH3; type of polymerisation: condensation
