Which statement best describes JavaScript?

• A. A markup language for styling pages.
• B. A server-side language for building backends.
• C. A scripting language that adds dynamic elements to a webpage.
• D. A protocol for network routing.

Answer: (C)

JavaScript is a scripting language used to make web pages interactive. It runs in the browser and can read and modify the page’s structure (the DOM), respond to user actions like clicks and keystrokes, and update content without reloading the page. This dynamic, client-side behavior is exactly what the description conveys. It’s not a markup language for styling (HTML) or a styling language (CSS), and it isn’t a network routing protocol. While JavaScript can also run on servers (Node.js), the core idea in this context is its role in adding dynamic elements to a webpage.
