Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CCCCn1c(O)c(C(CC)=Nc2ccc(OCC)cc2)c(=O)[nH]c1=O?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
[a] 8.983
[b] -2.295
[c] -4.027
[d] 19.670
Answer: c. -4.027\%.
{#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}.
