Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a compound with the SMILES CCOC(=O)CSc1nnc(NC(=O)c2cccc([N+](=O)[O-])c2)s1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
