Task: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(Nc1ccc(NC(=O)c2ccc([N+](=O)[O-])cc2[N+](=O)[O-])cc1)c1ccco1?
Constraint: You must return none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: 16.686
b: 9.274
c: 13.535
d: 15.342
e: 6.489
Answer: c. 13.535\%.
