Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CCOc1ccc(C2C(C#N)=C(N)N3C(=C2C#N)Sc2ccccc23)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a) 12.839
b) 14.591
c) 13.591
Answer: a. 12.839\%.
{#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:
