Which option is available in the page layout settings?

Margins are indeed an option available in the page layout settings. They refer to the spaces around the edges of the page where text and graphics cannot be placed. Adjusting margins is essential for creating a visually appealing and properly formatted document, as they help control the overall layout and ensure that content doesn't get too close to the edges of the page.

The other options, while relevant to document formatting, are typically not found in the page layout settings. Text orientation relates to how the text is positioned (horizontal or vertical) and is often set in the paragraph or text formatting options. Font style pertains to the typeface used in the document and is managed in the font settings. Caption style refers to the formatting of captions associated with images or tables and is typically adjusted in the specific formatting options for those elements.
