Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.767\% hERG inhibition at 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)CSc2n[nH]c(N)n2)c1
b) CC1=NN(CCc2ccccn2)C(=O)CC1
c) CS(=O)(=O)N1CCN(C(=O)c2ccc(Br)s2)CC1
d) CCOC(=O)c1cc(C(=O)NC(C)c2ccccc2)c(C)[nH]c1=O
Answer: b. CC1=NN(CCc2ccccn2)C(=O)CC1
