Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES O=C(N/N=C/c1c[nH]c2c1ccc1ccccc12)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: 10.826
b: -2.292
Answer: a. 10.826%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_10uM__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_10uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_10uM#}{herg_central_at_10uM__units}.
O=C(N/N=C/c1c[nH]c2c1ccc1ccccc12)c1ccc([N+](=O)[O-])cc1
O=C(N/N=C/c1c[nH]c2c1ccc1ccccc12)c1ccc([N+](=O)[O-])cc1
