Problem statement: Answer the multiple-choice question.
Query: Which compound has a 13.627\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)c1cccc(NC(=O)c2cn(-c3ccccc3)nc2-c2ccc([N+](=O)[O-])cc2)c1
[b] COC(=O)c1n[nH]n(-c2cc(Cl)cc(Cl)c2)c1=O
Answer: a. O=C(O)c1cccc(NC(=O)c2cn(-c3ccccc3)nc2-c2ccc([N+](=O)[O-])cc2)c1
