Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COCCN(C(=O)C(C)C)c1nnc(-c2ccc(C(C)(C)C)cc2)s1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a 9.648
b 4.175
c 20.929
Answer: a. 9.648\%.
