What option is used to remove existing header and footer content on the first page?

Choosing the option to use "Different First Page" effectively removes existing header and footer content specifically on the first page of a document. When this option is selected, it allows users to create a unique header and footer layout for the first page, which can be left blank or formatted differently than the rest of the document. This is particularly useful for cover pages or introductory pages where a standard header or footer may not be appropriate.

The benefit of using "Different First Page" is its targeted approach; it only affects the first page while leaving subsequent pages with the remaining header and footer content intact. This feature is commonly found in word processing software and is a standard option to customize document presentation, ensuring that documents can maintain a professional appearance.

The other choices, while they may seem related, do not function specifically to isolate the first page's headers and footers effectively as needed in this context. For example, simply using a section break could create a separate section for formatting but doesn't automatically clear the header or footer content on the first page as the "Different First Page" option does.
