Which option allows you to remove a page number from the first page of a document?

The option that allows you to remove a page number from the first page of a document is "Different First Page." When this feature is enabled in a word processing program like Microsoft Word, it provides the ability to set different headers and footers for the first page compared to the subsequent pages. This means that you can choose not to display a page number on the first page while still maintaining page numbers on the following pages.

This feature is particularly useful in documents where the first page might serve as a title page or cover page, which typically does not require a page number. The other choices do not specifically cater to the need to omit the page number on just the first page, which is why they don't serve this purpose.
