Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CCOc1ccc(C2C(C#N)=C(N)N(c3sc4c(c3C#N)CCCC4)C3=C2C(=O)CCC3)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] 12.557
[b] -4.762
[c] 1.068
Answer: b. -4.762%.
{#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}.
