Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.542\% 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] Cc1ccc2c(Cl)c(C(=O)Nc3ccc4c(c3)OCO4)sc2c1
[b] CCOC(=O)CC1=C(C(=O)OCC)C2(C(=O)Nc3ccccc32)C(C#N)=C(N)O1
[c] CC1(C)C(N(O)C(=O)Nc2ccccc2)N(c2cccc(Cl)c2)C(=O)N1O
[d] Cc1c(/C=N/n2cnnc2)c2ccccc2n1CCOc1ccccc1
[e] O=C(NCCCc1ccccc1)C1CC(=O)N(c2ccc3c(c2)OCCO3)C1
Answer: b. CCOC(=O)CC1=C(C(=O)OCC)C2(C(=O)Nc3ccccc32)C(C#N)=C(N)O1
