Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES COC(=O)c1cc(C(=O)Nc2ccc(Cl)cn2)cc([N+](=O)[O-])c1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] 12.434
[b] 4.960
[c] 3.508
[d] -15.439
Answer: b. 4.960\%.
