Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES COc1ccc(-n2c(C)cc(/C=C/c3nc(O)c([N+](=O)[O-])c(=O)[nH]3)c2C)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any additional words.
Options:
[a] -4.562
[b] 8.574
[c] 13.686
Answer: c. 13.686\%.
