Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a compound with the SMILES COc1ccc(-c2cc(-c3nnc(COC(=O)c4ccncc4)o3)c3ccccc3n2)cc1OC?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
