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=c1[nH]c(/C=C/c2ccccc2Cl)c([N+](=O)[O-])c(=O)[nH]1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a.) 4.277
b.) 7.058
c.) 12.217
d.) 1.785
Answer: b. 7.058%.
{#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:
