Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CCSc1nc(-c2ccccc2)c(C#N)c(=O)[nH]1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] 12.455
[b] 16.244
Answer: a. 12.455%.
