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=C1Nc2cc(C(=O)N3CCN(c4ccccn4)CC3)ccc2S/C1=C\c1ccccc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
