Problem statement: Answer the multiple choice question.
Question: Which compound has a -13.019\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a Brc1cccc(OCCCCN2CCCCC2)c1.O=C(O)C(=O)O
b O=C1OC(c2ccc([N+](=O)[O-])cc2)=N/C1=C/N1CC2CC(C1)c1cccc(=O)n1C2
Answer: b. O=C1OC(c2ccc([N+](=O)[O-])cc2)=N/C1=C/N1CC2CC(C1)c1cccc(=O)n1C2
