Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.485\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CCCc1cc(C(=O)NCCc2ccc(OC)c(OC)c2)no1
(b) CC(C)CN(CC(C)C)c1ccc(/C=N/n2cnnc2)cc1[N+](=O)[O-]
(c) O=C(Nc1ccccc1Cl)c1ccccc1Cl
(d) O=[N+]([O-])c1ccc2c(c1)/C(=N\O)c1ccccc1-2
(e) CCCCCCC1C(C#N)=C(N)OC2=C1C(=O)CC(C)(C)C2
Answer: b. CC(C)CN(CC(C)C)c1ccc(/C=N/n2cnnc2)cc1[N+](=O)[O-]
