Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CN1C(=O)C(O)(C2COC(C)(C)CC2=O)c2cc(Br)ccc21?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] 13.836
[b] -8.823
Answer: b. -8.823\%.
