Final answer:
In creating a single page InDesign document, the Number of Pages does not need to be selected. Page Size, Document Orientation, and Margins and Bleed Settings are essential for layout and printing.
Step-by-step explanation:
When creating a single page document in InDesign, the option that does not have to be selected is B) Number of Pages. Since the document is single page, there is no need to specify the number of pages as it is inherently one. However, the Page Size, Document Orientation, and Margins and Bleed Settings are essential to define the layout and printing requirements of the document.When creating a single page document in InDesign, the option that does not have to be selected is B) Number of Pages.When creating a single page document, you only need to select the Page Size, Document Orientation, and Margins and Bleed Settings. The number of pages is already determined as one.
For example, if you are creating a flyer for an event, you would choose the desired page size, such as letter or tabloid, set the orientation to either portrait or landscape, and adjust the margins and bleed settings. The number of pages is fixed to one because it is a single page document.
