Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 6.369\% 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] CCOC(=O)C1=C2N(C)c3ccccc3N2CCC1=O
[b] CN(C)C(C/C=N/OCc1c(Cl)cccc1Cl)=C(C#N)C#N
[c] COC(=O)c1ccccc1NC(=O)COC(C)=O
[d] CC(C)(C)NC(=O)CSc1ncnc2c1nnn2Cc1ccccc1Cl
[e] O=C(c1ccccc1)N1CCN(c2ncnc3c2cnn3-c2ccccc2)CC1
Answer: a. CCOC(=O)C1=C2N(C)c3ccccc3N2CCC1=O
