Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES O=C(Nc1ccc(-n2nncc2-c2ccco2)cc1)c1ccc(F)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a: -19.324
b: -1.988
c: 13.704
Answer: b. -1.988\%.
{#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#}?
