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 CN1C(=O)C2(C(C#N)=C(N)C(C#N)(C#N)C3=CCCCC32)c2ccccc21?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a -1.953
b -22.550
c 7.796
d 6.621
Answer: d. 6.621%.
{#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:
