Problem statement: Answer the multiple choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM of a compound with the SMILES O=c1ccnc(Sc2ncccc2[N+](=O)[O-])[nH]1?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
a) 12.256
b) 0.974
Answer: b. 0.974\%.
