Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES COc1ccc(Oc2nc3c(c(=O)n(C)c(=O)n3C)n2Cc2ccccc2)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
