Task: Answer the multiple-choice question.
Question: Which drug exhibits a -32.295% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CN(CC(=O)Nc1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1)C(=O)c1ccc(C#N)cc1
[b] O=[N+]([O-])c1ccc(CNc2cccc(F)c2)s1
Answer: b. O=[N+]([O-])c1ccc(CNc2cccc(F)c2)s1
