Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1ccc(OS(=O)(=O)c2ccc(N3C(=O)CCC3=O)cc2)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
a 20.671
b 7.176
c 18.227
Answer: a. 20.671\%.
