Problem statement: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CC(=O)C1=C(O)C(=O)N(c2ccc(O)cc2)C1c1cccc([N+](=O)[O-])c1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 14.459
b: 18.214
Answer: b. 18.214\%.
