Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a compound with the SMILES O=c1c(N=Nc2ccc(O)cc2)c(-c2ccccc2)[nH]n1-c1ccc([N+](=O)[O-])cc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a) 11.065
b) -1.305
c) -14.973
Answer: a. 11.065%.
{#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:
