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 CNC(=O)/C(C#N)=C/c1ccc(-c2ccccc2[N+](=O)[O-])o1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) 9.029
b.) -4.138
c.) 2.681
d.) 13.020
e.) 13.266
Answer: e. 13.266\%.
{#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}.
CNC(=O)/C(C#N)=C/c1ccc(-c2ccccc2[N+](=O)[O-])o1
CNC(=O)/C(C#N)=C/c1ccc(-c2ccccc2[N+](=O)[O-])o1
