Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES O=C(Cn1cnc([N+](=O)[O-])n1)N/N=C/c1cc(Cl)ccc1O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 3.278
b 5.512
Answer: a. 3.278%.
{#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.
