Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CC(=O)N(C)c1ccc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)cc1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] -57.452
[b] -13.489
Answer: b. -13.489%.
{#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:
