a: COc1ccccc1-n1c(SCC(=O)c2ccc(O)cc2O)nc2cc([N+](=O)[O-])ccc21
b: Cc1c(C(=O)N(C)C2CCCCC2)sc2ncnc(N3CCN(c4ccccc4F)CC3)c12
c: CCc1ccc(OCC(=O)N2CCc3ccccc32)cc1
d: Cc1ccc(CN(c2ccc(C(=O)NCC3CCCO3)cc2)S(C)(=O)=O)cc1
e: CN(C(=O)c1ccc(NC(=O)Cc2ccc(NC(=O)C3CCCN(C(=O)CCc4ccccc4)C3)cc2)cc1)C1CC1
Answer: b. Cc1c(C(=O)N(C)C2CCCCC2)sc2ncnc(N3CCN(c4ccccc4F)CC3)c12
