Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 1uM of a compound with the SMILES O=C(Cn1nc([N+](=O)[O-])nc1Br)NC(c1ccccc1)c1ccccc1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any additional words.
Options:

b: 23.361
c: 5.504
d: -11.161
e: 11.879
Answer: a. 8.475\%.
