Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.353\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(OC(=O)COc1ccccc1[N+](=O)[O-])C(=O)Nc1ccc(N2CCOCC2)cc1
b: COc1ccc(-c2nc(-c3ccc(NC(=O)c4ccc(Br)o4)cc3)no2)cc1OC
Answer: a. CC(OC(=O)COc1ccccc1[N+](=O)[O-])C(=O)Nc1ccc(N2CCOCC2)cc1
