Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES O=C(COC(=O)CN1C(=O)NC2(CCCC2)C1=O)Nc1ccc(C(F)(F)F)cc1[N+](=O)[O-]?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
[a] -12.774
[b] -0.173
Answer: b. -0.173%.
