Task: Answer the multiple-choice question.
Question: Which drug has a 12.811\% 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] CC(=O)O[C@H]1C(=O)[C@@]2(C)C([C@H](OC(=O)c3ccccc3)[C@]3(O)C[C@H](OC(=O)[C@H](O)[C@@H](NC(=O)c4ccccc4)c4ccccc4)C(C)=C1C3(C)C)[C@]1(OC(C)=O)CO[C@@H]1C[C@H]2O
[b] O=c1c(Cc2ccc(Cl)cc2)c(O)ccn1Cc1ccncc1
[c] CCOC(=O)C1=C(C(F)(F)F)Nc2ncnn2C1c1cc(OC)c(OC)cc1OC
Answer: c. CCOC(=O)C1=C(C(F)(F)F)Nc2ncnn2C1c1cc(OC)c(OC)cc1OC
