Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES CN1C2=CC=CC=CC2=[N+](C)C12C([N+](=O)[O-])=CC([N+](=O)[O-])=CC2=[N+]([O-])[O-]?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a -2.530
b 9.175
c -3.756
Answer: b. 9.175\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: What is the {herg_central_at_1uM__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_1uM%SMILES%}
Answer: {%multiple_choice_result}. {herg_central_at_1uM#}{herg_central_at_1uM__units}.
