Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1ccccc1C1C(C#N)=C(N)Oc2c1oc(CO)cc2=O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
(a) 0.727
(b) 9.496
Answer: a. 0.727\%.
{#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}.
