Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=c1ccnc(Nc2ccc([N+](=O)[O-])cc2)[nH]1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: -1.508
b: 9.764
c: 1.843
d: 19.838
e: 7.447
Answer: d. 19.838\%.
