Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.516% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccc2c3n([n+]([O-])c2c1)CCN=C3c1ccc(Cl)cc1
[b] Cn1ncc2c(Nc3cccc(Cl)c3)nc(Nc3cccc(Cl)c3)nc21
[c] O=C(c1cnn2c(C(F)F)cc(C3CC3)nc12)N1CCCC1
[d] O=C(NNC(=O)c1cccs1)c1cccnc1
Answer: b. Cn1ncc2c(Nc3cccc(Cl)c3)nc(Nc3cccc(Cl)c3)nc21
