Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES O=C(Nc1ccc(N2CCOCC2)cc1)Nc1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] -2.527
[b] 7.191
Answer: a. -2.527\%.
{#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.
