Task: Answer the multiple choice question.
Query: Which drug exhibits a -9.444\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Nc1nc2ncc(-c3ccsc3)c(N)n2n1
b: NC(=O)C1=C[C@@H](c2ccc(C(F)(F)F)cc2)C[C@@H](OCc2ccc(CO)cc2)O1
c: COc1cccc(NC(=O)C2CCCN2S(=O)(=O)c2ccc3c(c2)C(C)(C)C(=O)N3C)c1
Answer: a. Nc1nc2ncc(-c3ccsc3)c(N)n2n1
