Your mom is getting ready to cook dinner. She’s making mac and cheese. When she goes to the fridge to get the cheese, she sees that it’s gone! She starts yelling at you for eating the last of the cheese. You didn’t eat it. Your little sister did. How can you prove to your mom that it wasn’t you?

Lol!!

That actually happens with siblings...

If you don't have any proof, then ask your sister to tell the truth.

If she doesn't, then tell your mom that you don't care her yelling at you you because you have done nothing.

i think it may be b, i'm not exactly too sure on this. but b seems to make more sense.

the switch in narration increases the proximity of the narrator to the main character and the reader can perceive information only through the filter of a single character.
