What does HTML stand for?

HTML stands for HyperText Markup Language. This terminology is foundational in web development, as HTML is the standard markup language used to create the structure and content of web pages.

The term "HyperText" refers to the ability to link to other text or documents via hyperlinks, enabling navigation from one web page to another. "Markup Language" signifies that HTML is not a programming language but rather a system for annotating a document in a way that is machine-readable, allowing browsers to render text, images, and other elements properly.

Understanding this concept is crucial for anyone involved in web development, as HTML serves as the backbone for web content and presentation, interacting seamlessly with CSS (Cascading Style Sheets) and JavaScript to create dynamic and visually appealing websites. This definition illustrates why C is the correct answer in the context of web development and the role of HTML in it.
