Task: Answer the multiple choice question.
Question: Which drug has a -0.132\% 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, c, or d without using any other words.
Options:
a. CCN(c1ccccc1)S(=O)(=O)c1ccc(Cl)c(NC(=O)CSc2nncn2C)c1
b. CN(C)S(=O)(=O)N1CCN(c2ccccc2)CC1
c. COc1ccc(C(=O)Nc2cccc(-c3nc4ncccc4o3)c2C)cc1OC
d. CC1CCN(S(=O)(=O)c2cccc(C(N)=O)c2)CC1
Answer: b. CN(C)S(=O)(=O)N1CCN(c2ccccc2)CC1
