Task: Answer the MCQ question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a compound with the SMILES CCOC(=O)/C(C#N)=C/c1c(Oc2cccc(C)c2)nc2ccccn2c1=O?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] -46.847
[b] 0.542
Answer: a. -46.847%.
{#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:
{herg_central_at_10uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_10uM#}{herg_central_at_10uM__units}.
CCOC(=O)/C(C#N)=C/c1c(Oc2cccc(C)c2)nc2ccccn2c1=O
CCOC(=O)/C(C#N)=C/c1c(Oc2cccc(C)c2)nc2ccccn2c1=O
ethyl (E)-2-cyano-3-[2-(3-methylphenoxy)-4-oxopyrido[1,2-a]pyrimidin-3-yl]prop-2-enoate
