a. O=C(C1CCCO1)N1CCN(c2ncccn2)CC1
b. CN1CCN(c2c(F)cc3c(=O)c(C(=O)O)cn4c3c2SCC4)CC1.Cl
c. [O-]/[N+](=C/c1ccc(F)cc1)c1ccccc1
d. Cn1c(=O)n(C)c2cc([N+](=O)[O-])c(N3CCN(S(=O)(=O)c4ccccc4)CC3)cc21
e. Cc1c(C(=O)NNS(=O)(=O)c2ccccc2Cl)sc(=S)n1C
Answer: d. Cn1c(=O)n(C)c2cc([N+](=O)[O-])c(N3CCN(S(=O)(=O)c4ccccc4)CC3)cc21
