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(CN2CCN(S(C)(=O)=O)CC2)nc2cc([N+](=O)[O-])ccc21?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
a: -1.814
b: 16.663
c: -0.370
d: 11.712
Answer: c. -0.370%.
