Problem statement: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES O=C(NCC1CCN(C(=O)c2cccc([N+](=O)[O-])c2)CC1)c1cccc([N+](=O)[O-])c1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 21.017
b -53.481
Answer: b. -53.481%.
