What format is typically used for a web page?

The correct choice is HTML, which stands for HyperText Markup Language. HTML is the standard markup language specifically designed for creating and structuring content on the web. It allows developers to organize text, links, multimedia, forms, and other elements that present information to users in a web browser. HTML uses a system of tags to define elements, making it easier to design and structure web pages effectively.

While options like XML (eXtensible Markup Language) are used for data representation and storage rather than directly creating web pages, and CSS (Cascading Style Sheets) is employed for styling the appearance of web pages, they do not serve as the primary format for constructing the basic layout and content of a web page. PHP (Hypertext Preprocessor) is a server-side scripting language used to generate dynamic content and interact with databases, but it is not the format used to create static web pages. Thus, HTML stands as the fundamental framework upon which web pages are built.
