Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a drug with the SMILES COc1ccc(NC(=O)Cn2nc([N+](=O)[O-])c(Cl)c2C)cc1OC?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: 9.547
b: -2.141
c: 6.635
d: 12.928
e: 11.162
Answer: c. 6.635\%.
