Which of the following is a common file extension for HTML files?

• A. .html
• B. .xml
• C. .css
• D. .js

Answer: (A)

The file extension .html is commonly associated with HTML files, which are the backbone of web pages. When a file is saved with this extension, it indicates to the web browser that the file contains Hypertext Markup Language code, which is used to structure content on the web. Browsers interpret the code within these files to render text, images, links, and other media on a web page, making .html the standard for creating and displaying web documents. Other choices pertain to different file types: .xml is used for XML files that store and transport data, while .css is the extension for cascading style sheets that define the presentation of HTML documents. .js denotes JavaScript files that contain script code to add interactive functionality to web pages. Each of these formats plays a vital role in web development but serves a distinct purpose beyond creating the structured content that .html files provide.
