Task: Answer the multiple-choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a compound with the SMILES CC1=C(n2nnc([N+](=O)[O-])n2)C(c2cccnc2)C(C#N)=C(N)O1?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
(a) -5.583
(b) 29.770
(c) -3.787
(d) -11.953
Answer: a. -5.583%.
{#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}.
CC1=C(n2nnc([N+](=O)[O-])n2)C(c2cccnc2)C(C#N)=C(N)O1
CC1=C(n2nnc([N+](=O)[O-])n2)C(c2cccnc2)C(C#N)=C(N)O1
