Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.181\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCOc1ccccc1NC(=O)CCCc1ccc(OC)c(C)c1
[b] COCCCNCCOCCOc1ccc(Cl)cc1Br.O=C(O)C(=O)O
[c] CC(=O)Nc1ccc(/C=C(\C#N)C(=O)NC2CCCCC2C)cc1
[d] O=C(O)c1cccc(NC(=O)c2ccc3c(c2)C(=O)N(c2cccc([N+](=O)[O-])c2)C3=O)c1
Answer: d. O=C(O)c1cccc(NC(=O)c2ccc3c(c2)C(=O)N(c2cccc([N+](=O)[O-])c2)C3=O)c1
