Problem statement: Answer the multiple choice question.
Question: Which compound has a 16.671\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COC(=O)N/N=C(\C)c1ccc(C)c([N+](=O)[O-])c1
[b] COc1ccc(CCN2CC(C(=O)Nc3ccc4c(c3)OCO4)CC2=O)cc1OC
[c] O=C(Cc1ccccc1)Oc1ccc([N+](=O)[O-])cc1
Answer: c. O=C(Cc1ccccc1)Oc1ccc([N+](=O)[O-])cc1
