Task: Answer the multiple choice question.
Question: What is the human ether-à-go-go related gene (hERG) inhibition at 10uM of a drug with the SMILES Cn1c(=O)n(C)c2cc([N+](=O)[O-])c(N3CCN(C(=O)c4ccccc4Br)CC3)cc21?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:

b: 5.037
c: 9.362
d: -9.370
Answer: a. -70.562%.
