Problem statement: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES CC1CC(=O)N(c2ccc(NCc3ccc(Cl)cc3)c([N+](=O)[O-])c2)C1=O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
(a) 13.955
(b) -3.886
Answer: a. 13.955%.
