Problem statement: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C1NC(=O)/C(=C/c2ccc(-c3cccc([N+](=O)[O-])c3)o2)S1?
Constraint: You must return none, one or more options from a or b without using any additional words.
Options:
a) 20.432
b) -7.832
Answer: a. 20.432\%.
