Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 8.576\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CC(=O)Oc1ccc2occ(/C=N/c3cc(=O)[nH]c(=S)[nH]3)c(=O)c2c1
b: O=C(CCCC(=O)OCC(=O)c1ccccc1)Nc1cc(C(F)(F)F)ccc1Cl
c: COC(=O)c1ccc(CSc2nc3c(cnn3-c3ccc(C)cc3)c(=O)[nH]2)o1
Answer: b. O=C(CCCC(=O)OCC(=O)c1ccccc1)Nc1cc(C(F)(F)F)ccc1Cl
