What is HTML?

HTML stands for Hypertext Markup Language, which is foundational for creating the structure and layout of web pages. It provides a way to define elements on a webpage, such as headings, paragraphs, links, images, and more, using tags. These tags help browsers render content in a structured format, allowing users to view and interact with the web effectively.

Understanding HTML is crucial for anyone involved in web development, as it forms the backbone of web content. While it works in conjunction with other technologies like CSS for styling and JavaScript for interactivity, HTML itself is primarily concerned with the organization and presentation of information on the web. Therefore, recognizing HTML as a markup language specifically designed for this purpose makes the correct answer clear.
