Task: Answer the MCQ question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C1C(=Nc2ccc(OC(=O)c3ccccc3[N+](=O)[O-])cc2)C(n2nnc3ccccc32)=C(O)c2ccccc21?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a: 9.838
b: 0.843
Answer: b. 0.843\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_1uM__names__noun} of a {#compound|drug!} with the {SMILES__description} {SMILES#}?
Constraint: You must return none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{herg_central_at_1uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_1uM#}{herg_central_at_1uM__units}.
O=C1C(=Nc2ccc(OC(=O)c3ccccc3[N+](=O)[O-])cc2)C(n2nnc3ccccc32)=C(O)c2ccccc21
O=C1C(=Nc2ccc(OC(=O)c3ccccc3[N+](=O)[O-])cc2)C(n2nnc3ccccc32)=C(O)c2ccccc21
