Task: Answer the multiple choice question.
Question: Which compound has a 9.900\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COc1ccc(N2C(=O)CC(Nc3ccc(F)cc3)C2=O)c([N+](=O)[O-])c1
b O=C(NC(C(Cl)Cl)N1CCOCC1)c1ccccc1
Answer: b. O=C(NC(C(Cl)Cl)N1CCOCC1)c1ccccc1
