Final answer:
HTML is the primary language for creating web pages.
Therefore, the correct answer is: option d) HTML.
Step-by-step explanation:
HTML is a markup language, which means it is used to structure the content and layout of a web page. It consists of a series of elements and tags that define the structure and appearance of the page.
HTML is the foundation of the web and is supported by all web browsers. While other technologies like HTTP, URL, and JavaScript are essential for web development, they are not the primary languages used for creating web pages.
There are 142 HTML tags within the latest HTML version, HTML 5.2. Only 115 tags are deemed functional and usable within any HTML code.
These tags indicate the beginning and end of an HTML element that serves as a node within the DOM to define the structure of a webpage.
