Task: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a drug with the SMILES CN(C)c1cc[n+](CC(=O)Nc2ccc([N+](=O)[O-])cc2Cl)cc1.[Cl-]?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a.) -7.480
b.) 12.886
c.) 2.776
d.) 3.996
Answer: b. 12.886\%.
