Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES C=CCn1c([O-])c(C(C)=O)c(=O)[nH]c1=O.C[NH+](C)C?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] 8.546
[b] 18.685
Answer: a. 8.546\%.
{#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.
