Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.226\% 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(CCOC(=O)CNC(=O)c2ccc(Cl)cc2Cl)cc1
