b: 6.662
Answer: a. -5.077\%.
{#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}.
CC1=C(C(=O)OCc2ccccc2)C(c2ccsc2)C(C#N)=C(N)O1
CC1=C(C(=O)OCc2ccccc2)C(c2ccsc2)C(C#N)=C(N)O1
