Options:
(a) O=C(Nc1ccccc1)O/N=C1/CCCc2occc21
(b) COc1ccc([N+](=O)[O-])c(OC)c1C(=O)Nc1ccc(F)cc1F
(c) COc1ccc(C(=O)OCC(=O)N(C)C2CCS(=O)(=O)C2)cc1Br
(d) COc1ccc(CCN(C)C2CCCN(S(C)(=O)=O)C2)cc1OC
(e) CCOc1ccc(C(C(=O)NC2CCCCC2)N(C(=O)Cc2cccs2)c2ccc(-n3cnnn3)c(OC)c2)cc1
Answer: c. COc1ccc(C(=O)OCC(=O)N(C)C2CCS(=O)(=O)C2)cc1Br
