Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a compound with the SMILES COc1ccc(C2C([N+](=O)[O-])=C(N)Oc3c2c(=O)oc2ccccc32)cc1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 8.916
b: 12.646
Answer: a. 8.916\%.
{#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:
