a: COc1ccc(CN2CCN(C3CCOCC3)CC2CCO)c(C)c1C
b: CN(C)S(=O)(=O)c1ccc(N/C=C(\[N+](=O)[O-])S(=O)(=O)c2ccccc2)cc1
c: c1ccc(OCCCCn2cnc3ccccc32)cc1
d: O=C(CCCc1c[nH]c2ccccc12)NCc1cccs1
e: CCCCn1nnc(NC(=O)c2ccc(-c3cccc([N+](=O)[O-])c3)o2)n1
Answer: b. CN(C)S(=O)(=O)c1ccc(N/C=C(\[N+](=O)[O-])S(=O)(=O)c2ccccc2)cc1
