Which three technologies are used together to create Web pages that adapt to devices such as smartphones and smart TVs?

• A. HTML5, XML and JavaScript
• B. CSS, JavaScript and PHP
• C. HTML4, CSS2, JavaScript
• D. HTML5, CSS and JavaScript

Answer: (D)

This question focuses on how web pages adapt to different devices by combining structure, style, and behavior. HTML5 provides the semantic structure and content; CSS handles presentation and responsive layout, using techniques like media queries and flexible grids to rearrange and resize elements for phones, tablets, and TVs; JavaScript adds interactivity and runtime logic to adjust features based on the device. Together, HTML5, CSS, and JavaScript enable device-aware, responsive pages. XML is a data format, not the means to structure or style pages for different devices. PHP runs on the server to generate HTML, but adaptation for various devices happens in the browser with HTML, CSS, and JavaScript. HTML4 and CSS2 are older standards that lack many features modern responsive design relies on.
