Which row correctly shows the structure of a polymer and the monomers from which it is made?

1. Amonomers: HO–C(=O)–[grey square]–NH2; polymer: –C(=O)–[grey square]–C(=O)–N(H)–[grey square]–N(H)–
2. Bmonomers: H–C(H)=C(H)–C(H)=C(H)–H; polymer: –C(H)–C(H)–C(H)–C(H)–C(H)–C(H)– with H substituents
3. Cmonomers: HO–C(=O)–[grey square]–C(=O)–OH and H2N–[white square]–NH2; polymer: –O–C(=O)–[grey square]–C(=O)–O–N(H)–[white square]–N(H)–
4. Dmonomers: HO–C(=O)–[grey square]–C(=O)–OH and HO–[white square]–OH; polymer: –C(=O)–[grey square]–C(=O)–O–[white square]–O–
