Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a drug with the SMILES CCCCNC(=O)CSc1nnc(Cc2ccc(Cl)c(Cl)c2)c(=O)[nH]1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
[a] 15.928
[b] -9.427
Answer: a. 15.928%.
