Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.666% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CC(=O)Nc1ccc(S(=O)(=O)NCc2ccncc2)cc1
b.) CCN1C(=O)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
Answer: b. CCN1C(=O)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
