Task: Answer the multiple choice question.
Question: Which compound exhibits a -28.327% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(O)c1cccc(NC(=S)NC(=O)c2ccncc2)c1
[b] CCN(CC)c1ccc(/C=C(\C#N)C(=O)NCc2ccccc2)cc1
[c] CCOC(=O)C1CCN(C(=O)COC(=O)c2oc3ccccc3c2C)CC1
[d] CCn1nccc1C(=O)Nc1ccccc1OC
Answer: c. CCOC(=O)C1CCN(C(=O)COC(=O)c2oc3ccccc3c2C)CC1
