Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.554\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) COc1ccc(Cl)cc1S(=O)(=O)N1CCN(CC(=O)C(C)(C)C)CC1
