Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES O=C(CN(c1ccc(Cl)cc1)S(=O)(=O)c1ccc(Cl)c([N+](=O)[O-])c1)NCCc1ccc(F)cc1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a 11.568
b 13.335
Answer: a. 11.568\%.
{#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}.
