Task: Answer the multiple choice question.
Query: Which drug exhibits a -11.971% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCC(C)(C)n1nnnc1C(c1cccs1)N1CCc2ccccc21
b: CCOC(=O)c1c(NC(=O)COC(=O)CCS(=O)(=O)c2ccc(C)cc2)sc(C)c1C
c: O=C(CSc1ncn(-c2ccccc2)n1)N1CCN(c2ccccc2)CC1
Answer: b. CCOC(=O)c1c(NC(=O)COC(=O)CCS(=O)(=O)c2ccc(C)cc2)sc(C)c1C
