a CCOC(=O)c1ccc(Nc2nc(C)cc(=O)[nH]2)cc1
b C=CCn1c(NS(=O)(=O)c2ccccc2)c(S(=O)(=O)c2ccc(C)cc2)c2nc3ccccc3nc21
c O=C(Oc1ccc(/C=N/NC(=O)c2ccccn2)cc1)c1cccc(Br)c1
d CCCCC(=O)NNC(=O)c1c(O)c2ccccc2[nH]c1=O
e NS(=O)(=O)c1cc(C(=O)N2CCc3ccccc32)c(Cl)cc1Cl
Answer: b. C=CCn1c(NS(=O)(=O)c2ccccc2)c(S(=O)(=O)c2ccc(C)cc2)c2nc3ccccc3nc21
