Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES O=C(CCc1nc2ccccc2c(=O)[nH]1)N1CCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)CC1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 5.096
b: 6.091
Answer: a. 5.096%.
