Task: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CC(NC(=O)C(CC(=O)OC(C)(C)C)NC(=O)OC(C)(C)C)C(N)=O?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 7.223
b 12.816
Answer: a. 7.223\%.
{#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.
