Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.455\% 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: CCOc1ccc(-c2c(C#N)c(N)nc3c2c(=O)n(C)c(=O)n3C)cc1OC
b: CCS(=O)(=O)C(=C(Nc1ccc(OC)cc1)Nc1ccc(OC)cc1)S(=O)(=O)CC
c: CC(=O)C1=C(O)C(=O)N(CCc2c[nH]c3ccccc23)C1c1cccc(O)c1
Answer: b. CCS(=O)(=O)C(=C(Nc1ccc(OC)cc1)Nc1ccc(OC)cc1)S(=O)(=O)CC
