Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.052\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(Nc1ccccc1)C1=C(O)CC(c2ccoc2)CC1=Nc1ccccc1
b: CSc1ncccc1C(=O)N1CCCC(C(=O)c2ccc3ccccc3c2)C1
c: CN1CCN(c2nc3ccccn3c(=O)c2/C=C(\C#N)S(=O)(=O)c2ccccc2)CC1
Answer: c. CN1CCN(c2nc3ccccn3c(=O)c2/C=C(\C#N)S(=O)(=O)c2ccccc2)CC1
