Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -54.594% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CN(Cc1ccccc1)C(=O)C1CCN(S(=O)(=O)c2cc([N+](=O)[O-])ccc2Cl)CC1
(b) CSc1nc(N2CCCC2)c2c(c1C#N)CC(C)(C)OC2
(c) CC(C)N1CCc2c(sc(NC(=O)Cc3ccccc3)c2C#N)C1.Cl
Answer: a. CN(Cc1ccccc1)C(=O)C1CCN(S(=O)(=O)c2cc([N+](=O)[O-])ccc2Cl)CC1
