Answer:
The correct option is A)
Step-by-step explanation:
The tonality of the scene is gleeful, high spirited or cheerful.
The third and fifth sentences speak to this fact.
In the third sentence, the narrator states
"Oh, you would have laughed to see how cunningly I thrust in".
The sentence betrays that he or she has an expectation that if one could see him in the actual execution of this narrative, they most likely would find it hilarious. It is almost impossible to have an expectation of laughter from the audience when one themself are irritated or indifferent or curious.
In the fifth sentence, the narrator uses an exaggeration - "It took me an hour to place my whole head within the opening..."
Again, this gives the narrator away as being almost playful in his description of the event that took place, given that on the balance of probability, it is impossible for the action he describes to have actually taken an hour. Again, this is an attempt to project his cheerfulness onto the reader, given that exaggeration is one of the tools of comedy.
Cheers!
