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 CC(C)CC(=O)NC(=S)N1CCN(c2ccc([N+](=O)[O-])cc2Cl)CC1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
