Problem statement: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES CC1CN(c2ccc([N+](=O)[O-])c(NCCOc3ccccc3)c2)CC(C)N1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:

[b] 3.734
[c] -26.884
[d] 18.385
[e] -0.440
Answer: c. -26.884%.
