Problem statement: Answer the multiple choice question.
Question: Which compound has a -0.518\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1ccc(N2CCN(CCCNC(=O)CCC(=O)N3CCOc4ccc(Cl)cc43)CC2)cc1
[b] O=C(c1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)N1CCN(Cc2ccccc2)CC1
[c] C=C(C)CNC(=S)N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12
Answer: c. C=C(C)CNC(=S)N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12
