Task: Answer the MCQ question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES COCCNC(=O)/C(C#N)=C/c1c(N2CC(C)OC(C)C2)nc2ccccn2c1=O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 20.698
b: -0.670
Answer: b. -0.670%.
{#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}.
COCCNC(=O)/C(C#N)=C/c1c(N2CC(C)OC(C)C2)nc2ccccn2c1=O
COCCNC(=O)/C(C#N)=C/c1c(N2CC(C)OC(C)C2)nc2ccccn2c1=O
