Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.579% 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 CC1(C(=O)O)COC(c2ccc(Cl)cc2)OC1
b COc1ccc(C(=O)Nc2ccc(-c3nnn(CC(=O)NCc4ccco4)n3)cc2)cc1
c CC(=O)Oc1ccc2c(c1)Oc1cc(OC(C)=O)ccc1C21OC(=O)c2ccccc21
Answer: c. CC(=O)Oc1ccc2c(c1)Oc1cc(OC(C)=O)ccc1C21OC(=O)c2ccccc21
