Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.247% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COc1cc(C2NC(=O)NC(c3ccccc3)=C2C(C)=O)cc([N+](=O)[O-])c1O
[b] CC(C)C1C(c2ccccc2)NC(c2ccccc2)CC1(O)c1ccc(F)cc1.Cl
Answer: b. CC(C)C1C(c2ccccc2)NC(c2ccccc2)CC1(O)c1ccc(F)cc1.Cl
