Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1ccc(C2C(C#N)=C(N)Oc3cc(C)[nH]c(=O)c32)cc1OC?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] 5.647
[b] 13.102
Answer: a. 5.647\%.
{#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.
Options:
{herg_central_at_1uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_1uM#}{herg_central_at_1uM__units}.
COc1ccc(C2C(C#N)=C(N)Oc3cc(C)[nH]c(=O)c32)cc1OC
COc1ccc(C2C(C#N)=C(N)Oc3cc(C)[nH]c(=O)c32)cc1OC
