Task: Answer the multiple choice question.
Query: Which drug exhibits a -49.275% 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(CN1CCN(S(=O)(=O)N2CCOCC2)CC1)Nc1ccc(Cl)c(Cl)c1
(b) COc1ccc(C2(C)NC(=O)N(CC(=O)Nc3cccnc3Cl)C2=O)cc1
(c) CC(=O)CC1(O)C(=O)Nc2ccccc21
Answer: a. O=C(CN1CCN(S(=O)(=O)N2CCOCC2)CC1)Nc1ccc(Cl)c(Cl)c1
