In word processing software such as Microsoft Word, switching between portrait and landscape page orientation is done through which feature?

Introduction / Context:
This question focuses on page orientation settings in word processing software. When creating documents, users may need to print on tall pages, called portrait orientation, or wide pages, called landscape orientation. Knowing where to change this setting is part of practical computer skills for office work and exams.

Given Data / Assumptions:

• The software is a word processor such as Microsoft Word.
• The task is switching between portrait and landscape modes.

Concept / Approach:
The page orientation setting is part of page layout configuration, not part of the content editing view or header footer tools. In Microsoft Word, such options are typically found under Page Setup or the Page Layout group, where users can choose portrait or landscape orientation. The print layout view controls how the page is displayed on screen but does not itself change orientation. The header and footer toolbar is used for editing content at the top and bottom of pages. Arc map is unrelated to standard word processors.

Step-by-Step Solution:
Step 1: Identify that page orientation is fundamentally a page setup property affecting the entire document or selected sections. Step 2: Examine option D, page setup dialog box, which is exactly where orientation settings are found in many versions of Word. Step 3: Examine option A, print layout view. This view shows the document as it will appear when printed, but orientation changes are made through settings, not by just switching views. Step 4: Examine option C, header and footer toolbar. This tool is for editing headers and footers, not for changing orientation. Step 5: Examine option B, arc map, which is not a feature of Word page setup at all.

Verification / Alternative check:
If you open Word and wish to change orientation, you typically go to the Layout or Page Layout tab and choose Orientation, which internally uses page setup settings. The dialogues and menu labels refer to page setup when configuring margins, paper size, and orientation. This confirms that page setup is the correct place to perform the operation described in the question.

Why Other Options Are Wrong:
Print layout view: This is wrong because a view controls how you see the document on screen but does not, by itself, change the orientation of pages. Orientation change is still done via page setup options.
Arc map: This is wrong because it is not a standard term or tool in word processing. It may refer to unrelated mapping software but has nothing to do with page orientation in Word.
Header and footer toolbar: This is wrong because it allows you to insert and modify header and footer content, page numbers, and similar elements. It does not contain the commands to switch between portrait and landscape orientation.

Common Pitfalls:
Some users confuse what they see with the underlying settings and think that changing the view mode alters page layout properties. Others may spend time searching in header or footer tools for layout options. The key is to remember that anything involving margins, paper size, or orientation is found under page setup or layout menus, not under content editing toolbars.

Final Answer:
Switching between portrait and landscape page orientation is done through the Page setup dialog box.
