Task: Answer the multiple-choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES CCN1C(=O)NC(=O)/C(=C\c2cn(CC(=O)N3CCCC3)c3ccccc23)C1=O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
(a) 13.977
(b) 7.422
Answer: a. 13.977\%.
{#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.
