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 compound with the SMILES OC(CN1C2=NCCN2c2ccccc21)c1ccc(Br)cc1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] -62.972
[b] -2.788
Answer: a. -62.972\%.
