Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.924% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(Nc1ccc([N+](=O)[O-])cc1)c1cn(-c2ccccc2)nc1-c1cc2ccccc2o1
b: Cl.Clc1ccc(Cn2c(CN3CCCC3)nc3ccccc32)cc1
c: CCN(CC)CC(C)C(C)OC(=O)C(O)(c1ccccc1)c1ccccc1.Cl
Answer: a. O=C(Nc1ccc([N+](=O)[O-])cc1)c1cn(-c2ccccc2)nc1-c1cc2ccccc2o1
