Task: Answer the multiple-choice question.
Query: Which compound exhibits a 16.550\% 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 other words.
Options:
(a) O=C(Nc1nc2ccccc2s1)Nc1ccc([N+](=O)[O-])cc1Cl
(b) COc1cc(OC)c(C2C(C(=O)N3CCOCC3)=C(C)NC3=C2C(=O)CC(C)(C)C3)cc1OC
Answer: b. COc1cc(OC)c(C2C(C(=O)N3CCOCC3)=C(C)NC3=C2C(=O)CC(C)(C)C3)cc1OC
