Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES Nc1nn(-c2ccccc2)c(N)c1N=Nc1cccc(F)c1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a 18.685
b 16.894
c 1.197
Answer: a. 18.685\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
