Task: Answer the multiple choice question.
Query: Which compound has a -76.447\% 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] Cc1cc(OCCn2cncn2)ccc1[N+](=O)[O-]
[b] O=C(COc1ccc(Cl)cc1)N1CCN(Cc2ccc([N+](=O)[O-])cc2)CC1.O=C(O)C(=O)O
Answer: b. O=C(COc1ccc(Cl)cc1)N1CCN(Cc2ccc([N+](=O)[O-])cc2)CC1.O=C(O)C(=O)O
