Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a drug with the SMILES O=C(Nc1cc([N+](=O)[O-])ccc1F)c1ccc2c(c1)OCCO2?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: -4.246
b: 21.605
Answer: b. 21.605%.
{#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:
