Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 16.843\% 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, d, or e without using any other words.
Options:
[a] O=C(COc1ccccc1)N1CCN(c2ccc([N+](=O)[O-])c(N3CCCCC3)c2)CC1
[b] O=[N+]([O-])c1cccnc1Sc1ccccc1Cl
[c] COC(=O)C1=C2SCC(=O)N2C(N)=C(C#N)C1
[d] COC(=O)c1ccc(-c2nc(-c3ccc(Br)o3)no2)cc1
[e] Oc1c(N=Nc2ccc(F)cc2)ccc2ccccc12
Answer: b. O=[N+]([O-])c1cccnc1Sc1ccccc1Cl
