Task: Answer the multiple-choice question.
Question: Which drug has a 20.388\% 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] O=C(O)CN1C(=O)c2ccc(Oc3ccc([N+](=O)[O-])cc3)cc2C1=O
[b] CC1=CN2C(=N)/C(=C/c3ccco3)C(=O)N=C2S1
[c] CN(C)c1ccc(CN(C(=O)c2cccs2)C2CCS(=O)(=O)C2)cc1
[d] Cc1ccc(-n2cc(CN3CCN(Cc4nccn4C)CC3)c(-c3cccc(C)c3)n2)cc1
[e] C[C@H](NC(=O)c1ccccc1)C(=O)OCC(=O)Nc1ccc2c(c1)OCO2
Answer: a. O=C(O)CN1C(=O)c2ccc(Oc3ccc([N+](=O)[O-])cc3)cc2C1=O
