Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.792% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(CSc1nc2ncc(Br)cc2[nH]1)c1cccc([N+](=O)[O-])c1
b: O=C(Nc1cccc2ccccc12)c1ccc([N+](=O)[O-])s1
c: CN(CCOc1ccc(Cl)cc1)C(=O)c1ccc2c(=O)n3c(nc2c1)CCC3
d: c1ccc(OCc2nnc(-c3ccccc3)o2)cc1
Answer: b. O=C(Nc1cccc2ccccc12)c1ccc([N+](=O)[O-])s1
