Hello! I would say your answer is C, court opinion.
A court opinion is something used in court - it announces the final decision of the judge, as well as restates a lot of the important parts of the court case. This has to do with the law, so it should be very formal.
On the other hand, a letter to your grandmother should be casual as it is a personal matter. A newspaper article is going to be as formal, but it is not regarded with as high importance as something on the legal side. An instruction manual will also be formal, but, same reasoning as a newspaper article.
Hope this helps!
Dude, You can do that. That really easy. It only 80 words. Plus it's a diary so it's not complex. You can literally make it up too. You could say your first day at McDonald's or first day working at a candy store.
1st person because if they use "I' it is first. Good way to remember it
Personification.
Rubs is the key word because smoke can't really rub things like a human, so it's personifying human behavior.
Hope that helps!
