Task: Answer the multiple-choice question.
Question: Which compound has a 0.997\% human ether-à-go-go related gene (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: O=C(Cc1ncc(C(F)(F)F)cc1Cl)N1CCN(c2cccc(Cl)c2)CC1
b: CCOC(=O)CSC1=C(C#N)C(c2ccco2)C(C(=O)Nc2cccc(C(F)(F)F)c2)=C(C)N1
c: COc1ccc(C(N)CCc2ccco2)cc1.Cl
Answer: b. CCOC(=O)CSC1=C(C#N)C(c2ccco2)C(C(=O)Nc2cccc(C(F)(F)F)c2)=C(C)N1
