Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a compound with the SMILES O=C(NCCO)c1cc(-c2cc(C(=O)NCCO)c3ccccc3n2)nc2ccccc12?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] 5.677
[b] 12.649
Answer: a. 5.677\%.
{#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.
