Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES O=C(c1ccc(CN2CCc3ccccc3C2)cc1)N1CCN(c2ccc(F)cc2)CC1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
