Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(O)[C@H](Cc1ccccc1)Nc1ccc([N+](=O)[O-])cn1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a -2.509
b 9.625
Answer: b. 9.625\%.
{#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.
