Task: Answer the multiple-choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(N/N=C/c1ccc(Br)s1)c1cccc([N+](=O)[O-])c1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any other words.
Options:

b: 12.395
c: 13.232
d: 5.874
e: 13.498
Answer: b. 12.395\%.
