Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(CCn1nnc2ccccc21)OCC(=O)c1ccc([N+](=O)[O-])cc1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] 5.760
[b] 8.274
Answer: b. 8.274\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
