In this play, the attorney is trying to find out what happened to Mr. Wright and how he died (apparently strangled, but suspected murdered). Mrs. Peters finds the bird, that was supposed to be in the bird cage, strangled. She interprets this as the preparation to the killing of Mr. Wright and hides the bird in a box. The fact that the ladies in the scene have agreed to not disclose the contents of the box and continue to hide it, let us know that the best answer here is option C.
Sorry I am not sure of the question
If the story would have been from Laurie's perspective, A. The audience would have been afraid of Laurie's mother because Laurie is so afraid of her, and C. The audience might have known that Laurie was misbehaving at school and making up the "Charles" character to mislead his mother.
It is clear that Laurie is afraid of his mother, he wouldn't have invented Charles to cover up for his misbehaving otherwise. This fear would have appear in the story, as well as the truth of his behaviour.
