Task: Answer the multiple choice question.
Query: Which drug has a 15.195% 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. O=C(Oc1ccc(C(=S)N2CCOCC2)cc1)c1ccc(Cl)cc1
b. CC1(C)CC(=O)C([N+](=O)[O-])=C(NCCCO)C1
Answer: b. CC1(C)CC(=O)C([N+](=O)[O-])=C(NCCCO)C1
