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 Nc1ncc2c(n1)CCN(c1ccc([N+](=O)[O-])cc1)C2?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a 5.082
b -41.914
c 6.425
d -4.401
Answer: d. -4.401\%.
