Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a compound with the SMILES O=c1ccc2ccc(Oc3ccc([N+](=O)[O-])cc3Cl)cc2o1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: -5.377
b: 6.977
c: -1.543
d: 5.536
e: 9.192
Answer: d. 5.536%.
