Task: Answer the multiple choice question.
Query: Which compound has a -0.740\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCOc1ccc(NC(=O)[C@@H](NC(=O)c2ccccc2)[C@@H](C)CC)cc1
[b] O=C(NCCNC(=O)c1cc(OCC(F)(F)F)ccc1OCC(F)(F)F)Nc1cccc(C(F)(F)F)c1
[c] CC(C)(C)OC(=O)N1CCC[C@H]1c1nnc(SCc2cccc(Cl)c2)o1
Answer: b. O=C(NCCNC(=O)c1cc(OCC(F)(F)F)ccc1OCC(F)(F)F)Nc1cccc(C(F)(F)F)c1
