Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES O=C(Cn1nnc(-c2ccncc2)n1)Nc1ccc2c(c1)CCC2?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
