Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES O=C(CSc1ncnc2nc[nH]c12)c1ccc([N+](=O)[O-])cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] -73.913
[b] -8.668
[c] 18.572
Answer: c. 18.572%.
{#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}.
