Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES CCn1c(=O)n(CC)c2cc(S(=O)(=O)NCCOc3ccccc3)c(C)cc21?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a: 13.306
b: 12.495
Answer: b. 12.495\%.
