Task: Answer the multiple choice question.
Query: Which drug has a 6.430\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) COc1cc(S(=O)(=O)NCc2ccncc2)c(OC)cc1C
(b) O=C(Nc1nc(-c2ccccn2)cs1)C12CC3CC(CC(O)(C3)C1)C2
Answer: a. COc1cc(S(=O)(=O)NCc2ccncc2)c(OC)cc1C
