Task: Answer the multiple-choice question.
Query: Which compound has a 1.258\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)C3)c(OC)c1OC
[b] COc1ccc(Nc2nnc(-c3ccccc3)c3ccccc23)cc1C(=O)N1CCCCC1
[c] C=CCN1C(=O)C(CC(=O)Nc2ccccc2)N(Cc2ccccn2)C1=S
[d] O=C(NCc1ccccc1)c1ccc(CSc2ccccc2)o1
[e] O=C(NC1CCCc2ccccc21)N[C@@H](Cc1ccccc1)C(=O)O
Answer: c. C=CCN1C(=O)C(CC(=O)Nc2ccccc2)N(Cc2ccccn2)C1=S
