Task: Answer the multiple choice question.
Question: Which compound exhibits a -43.947\% 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 COC(=O)c1cc2sc(Cl)cc2n1CC(=O)Nc1ccc(OC)c(OC)c1OC
b O=c1c2c(-c3ccc([N+](=O)[O-])cc3)csc2nc2n1CCC2
c O=C(O)c1cc(O)ccc1NC(=O)c1cccc2ccccc12
Answer: b. O=c1c2c(-c3ccc([N+](=O)[O-])cc3)csc2nc2n1CCC2
