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 Cc1[nH]c(=O)c(C#N)c(C)c1[N+](=O)[O-]?
Constraint: You must return none, one or more options from a or b without using any other words.
Options:
(a) -0.018
(b) -51.618
Answer: a. -0.018\%.
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
