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(COc1ccc(F)cc1F)NNC(=O)Nc1cccc([N+](=O)[O-])c1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] 5.477
[b] 5.360
[c] 14.270
[d] 13.228
Answer: a. 5.477\%.
{#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}.
O=C(COc1ccc(F)cc1F)NNC(=O)Nc1cccc([N+](=O)[O-])c1
O=C(COc1ccc(F)cc1F)NNC(=O)Nc1cccc([N+](=O)[O-])c1
