Task: Answer the multiple choice question.
Query: Which drug exhibits a 27.057% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1cc(C2CC(=O)C=C(O)C2)cc(OC)c1OC
[b] CCC(O)(c1ccc(Br)cc1)C(CNCCCCO)c1ccccc1.Cl
[c] CC(C)Cn1c(CNC(=O)c2ccccc2)nc2ccccc21
Answer: a. COc1cc(C2CC(=O)C=C(O)C2)cc(OC)c1OC
