Task: Answer the multiple choice question.
Query: Which drug exhibits a -18.127% 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. COC(=O)c1ccc(CNC(=O)COC(=O)Cc2ccsc2)cc1
b. COc1ccc(CN(C)C(=O)CCC(=O)c2cc(C)sc2C)c(OC)c1OC
c. O=C1C=C(c2ccc(Cl)nc2)C[C@@H](c2ccc3c(c2)OCO3)C1
Answer: b. COc1ccc(CN(C)C(=O)CCC(=O)c2cc(C)sc2C)c(OC)c1OC
