Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 8.401\% 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 additional words.
Options:
[a] COc1ccc(O)c(C(=O)c2cnn(-c3ccc(Cl)cc3)c2)c1
[b] COc1ccccc1-c1nnc(SCC(=O)Nc2nc(-c3ccccc3)cs2)n1C
[c] Cc1ccc(-c2cc(Cc3ccncc3)c(=O)[nH]n2)cc1
[d] O=C(CNC(=O)C12CC3CC(CC(C3)C1)C2)OCC(=O)N1CCCCC1
[e] COc1ccc(C2(C#N)CCC(=O)N2c2ccccc2)cc1
Answer: e. COc1ccc(C2(C#N)CCC(=O)N2c2ccccc2)cc1
