Which type of digital document is known for maintaining its layout across different devices?

• A. Word document
• B. HTML page
• C. PDF document
• D. Text file

Answer: (C)

The correct choice is the PDF document because it is specifically designed to preserve the formatting, layout, and appearance of the original content regardless of the device or software used to view it. This means that a PDF will look the same on a computer, tablet, or smartphone, ensuring that the fonts, images, and overall layout remain intact.

In contrast, a Word document's formatting may change depending on the software version or device used to open it, leading to variations in appearance. An HTML page relies on web browsers to render the content, which can differ from one browser to another or based on the device's screen size. Text files contain only plain text with no formatting or layout features, which do not allow for any layout preservation when viewed across different devices.

Overall, the PDF format is the ideal choice for maintaining a consistent and professional appearance of digital documents.
