Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES CC(=O)Nc1ccc(Nc2nc(C)c([N+](=O)[O-])c(Nc3ccc(NC(C)=O)cc3)n2)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
(a) 5.883
(b) 12.958
(c) 20.683
Answer: c. 20.683\%.
