The correct answer is A: Through his constant questions.
In "The Storyteller," by Saki (H. H. Munro), Cyril keeps irritating Aunt and making difficult questions during a train journey. She is so annoyed that she decides to tell the children an unoriginal story, which does not satisfy them. As a result, the Bachelor joins the conversation and tells them a story that does not involve a happy ending, which Aunt finds improper and the children amusing.
H. H. Munro, also known by his pen name "Saki", was born in Burma but had to move to England after the sudden death of his mother. His stories are usually a criticism and a satire of the Edwardian England in which he grew up .In "The Storyteller" he satirizes society's values when it comes to raising and educating children. He uses the constant questions posed by Cyril to contribute to the satire of the story and to allude to the theme of questioning authority.
