Task: Answer the multiple-choice question.
Question: Which drug has a -6.929\% 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: CN(c1cccc(NC(=O)CN(c2cccc(Cl)c2)S(=O)(=O)c2ccc(Cl)cc2)c1)S(C)(=O)=O
b: CN(C)CC(O)COc1ccc(-c2ccc(C#N)cc2)cc1
c: CCN1CCN(C(=O)c2ccc(OC)c(S(=O)(=O)Nc3ccc(C)cc3)c2)CC1
Answer: b. CN(C)CC(O)COc1ccc(-c2ccc(C#N)cc2)cc1
