Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=c1/c(=C/c2ccco2)sc2n1CN(c1cccc(Br)c1)CN=2?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] 12.448
[b] 12.008
Answer: a. 12.448\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
