Task: Answer the multiple-choice question.
Question: Which drug exhibits a -13.633% 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 COc1ccc(CNC(=O)c2ccc[nH]2)cc1Cl
b O=C(c1cc(COc2ccc(F)cc2Cl)on1)N1CCC(c2ccncc2)CC1
c COC(=O)c1nn(-c2ccccc2)c(=O)cc1Oc1ccc(Cl)cc1
Answer: c. COC(=O)c1nn(-c2ccccc2)c(=O)cc1Oc1ccc(Cl)cc1
