Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES O=C(Nc1c[nH]c(=O)[nH]c1=O)c1ccc([N+](=O)[O-])cc1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
(a) 10.016
(b) 22.432
(c) 9.936
(d) 3.079
Answer: a. 10.016%.
{#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}.
