Task: Answer the multiple-choice question.
Query: Which drug exhibits a -5.855% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1ccc(-c2cc(C3CCN(c4ncccc4[N+](=O)[O-])CC3)[nH]n2)cc1
b: CC1(c2ccccc2Cl)NC(=O)N(CC(=O)Nc2ccc(N3CCCCC3)cc2)C1=O
Answer: a. COc1ccc(-c2cc(C3CCN(c4ncccc4[N+](=O)[O-])CC3)[nH]n2)cc1
