Question

1. MLA style requires that you create a header for each page that contains which of the following? A. Your last name and page number B. Your last name and title C. Your last name, title, and page number D. Your last name, first name, and page number

Answer 1

The answer is A. your last name and page number
In the letter particularly, last name usually put as an introduction before the initial content of the letter, so it will be better if created with header.
For page that contains page number, the header is created to give a pointer on what the page number means/indicates
