Task: Answer the multiple choice question.
Query: Which compound exhibits a -10.802\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=c1cc(-c2ccco2)nc(-c2cccs2)o1
b. CN(C)C(/C=C/Nc1ccc([N+](=O)[O-])cc1)=C(C#N)C#N
Answer: b. CN(C)C(/C=C/Nc1ccc([N+](=O)[O-])cc1)=C(C#N)C#N
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?
Constraint: You must select none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
Options:
{SMILES%herg_central_at_1uM%}
Answer: {%multiple_choice_result}. {SMILES#}
CN(C)C(/C=C/Nc1ccc([N+](=O)[O-])cc1)=C(C#N)C#N
CN(C)C(/C=C/Nc1ccc([N+](=O)[O-])cc1)=C(C#N)C#N
