Task: Answer the multiple-choice question.
Query: Which compound exhibits a -20.768% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) CN(C(=O)c1ccc(S(=O)(=O)c2cccc(Cl)c2)c([N+](=O)[O-])c1)C1CCCCC1
b) CC(=O)c1c(O)cc(C(C)C)n(-c2ccccc2)c1=O
Answer: a. CN(C(=O)c1ccc(S(=O)(=O)c2cccc(Cl)c2)c([N+](=O)[O-])c1)C1CCCCC1
