Task: Answer the multiple-choice question.
Question: Which compound has a 5.969% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CC(=O)Nc1ccc(N=c2cc([N+](=O)[O-])cc(Cl)n2O)cc1
b C=CCNC1=C(Cl)C(=O)N(Cc2ccccc2)C1=O
Answer: a. CC(=O)Nc1ccc(N=c2cc([N+](=O)[O-])cc(Cl)n2O)cc1
