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 compound with the SMILES CCCn1c(=O)n(C)c(=O)c2c(SC(C)C(=O)NCC3CCCO3)nc(CC(C)C)nc21?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
