Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a drug with the SMILES O=C(NNC(=O)c1c(O)c2ccccc2[nH]c1=O)c1ccccc1Br?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
[a] -6.942
[b] 14.910
[c] 22.741
[d] -17.913
Answer: a. -6.942%.
{#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:
{herg_central_at_10uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_10uM#}{herg_central_at_10uM__units}.
O=C(NNC(=O)c1c(O)c2ccccc2[nH]c1=O)c1ccccc1Br
O=C(NNC(=O)c1c(O)c2ccccc2[nH]c1=O)c1ccccc1Br
