Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a compound with the SMILES CCCc1c(C)nn(C(=O)/C(C#N)=N/Nc2ccccc2[N+](=O)[O-])c1C?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a. 13.156
b. 20.427
c. 15.897
Answer: c. 15.897\%.
{#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.
