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(NC(NNc1ccc([N+](=O)[O-])cc1)(C(F)(F)F)C(F)(F)F)c1ccc(Cl)cc1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 5.378
b: 13.740
Answer: a. 5.378\%.
{#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:
