Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.165% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1ccc(OC)c(N2C(=O)/C(=C/c3ccco3)C(=O)NC2=S)c1
[b] O=Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ncccn12
[c] Cc1c(Cl)cccc1NC(=O)CCCN1C(=O)CCC1=O
Answer: b. O=Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ncccn12
