a.) O=C(NN1C(=O)C2C3C=CC(O3)C2C1=O)c1ccccc1
b.) COc1ccc(OCC(O)CN2CCCCC2)cc1.Cl
c.) NC(=O)CC(NC(=O)c1ccc(Br)cc1)c1ccc(N2CCN(c3ccccn3)CC2)c([N+](=O)[O-])c1
d.) Cc1c(NC(=O)c2ccc(S(=O)(=O)N(C)C)cc2)cccc1-n1cnnn1
e.) CC1(C)Oc2ccc(C(=O)NN)cc2NC1=O
Answer: c. NC(=O)CC(NC(=O)c1ccc(Br)cc1)c1ccc(N2CCN(c3ccccn3)CC2)c([N+](=O)[O-])c1
