Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.071% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CC(=O)CC(c1ccccc1)C1(Cl)C(=O)c2ccccc2C1=O
(b) COc1ccccc1Cn1[nH]nnc1=S
(c) O=C(CNC(c1ccccc1)c1ccccc1)Nc1cc([N+](=O)[O-])ccc1Cl
Answer: b. COc1ccccc1Cn1[nH]nnc1=S
