Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 8.664\% 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) CCc1ccc([C@@H]2CC=C(C(=O)O)[C@H](c3ccccc3)N2S(=O)(=O)c2ccc(C)cc2)cc1
