The moderate margin of a page in MS Word can be applied to the page from which of the following?

The correct answer is Page Layout Tab.

Step-by-Step Explanation:

1. In Microsoft Word, page setup options such as margins, orientation, size, and columns are managed under the Page Layout tab (or simply Layout tab in newer versions of MS Word).

2. To apply predefined margin settings like Moderate, Normal, Narrow, or Wide, navigate to the Page Layout tab, click on the Margins button in the Page Setup group, and select the desired margin preset (e.g., Moderate).

3. Let's look at why the other options are incorrect:
- Review tab: Used for proofing tools, comments, tracking changes, and document protection.
- Design tab: Used for changing document themes, color schemes, page background color, and page borders.
- View tab: Used for toggling different views (e.g., Print Layout, Web Layout), showing rulers/gridlines, and adjusting zoom level.
