Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.287\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1ccc(/C=N\Nc2ccc([N+](=O)[O-])cc2)c(C(=O)O)c1OC
[b] Nc1c(-c2ccc(Cl)cc2)cnn1-c1ccc(Cc2ccc(Cl)cc2Cl)nn1
[c] COc1ccc(NC(=S)Nc2ccc(F)cc2)cc1
[d] O=[N+]([O-])c1cccc(S(=O)(=O)NCCc2cn3ccccc3n2)c1
[e] Cc1cc(N2CCCC2)nc2ccc(NC(=S)NC(C)C)cc12
Answer: b. Nc1c(-c2ccc(Cl)cc2)cnn1-c1ccc(Cc2ccc(Cl)cc2Cl)nn1
