Which statement about HTML5 is true?

• A. HTML5 does not require third-party plug-ins for video and audio content.
• B. HTML5 requires plug-ins for video.
• C. HTML5 prohibits video playback on mobile.
• D. HTML5 only supports audio if a plug-in is installed.

Answer: (A)

HTML5 introduces native video and audio elements, which let browsers play media without third-party plug-ins. By using the video (or audio) tag and providing sources in formats the browser can decode (like MP4, WebM, or Ogg), the browser uses its built-in player and codecs, so users don’t need any external plug-ins such as Flash. This native support is what makes HTML5 multimedia more portable and reliable across different devices and browsers. In practice, you’ll often provide multiple formats to cover codec differences, and you’ll also deal with things like autoplay or user-triggered playback on mobile. The statements that claim plugins are required, that video isn’t allowed on mobile, or that audio only works with a plugin aren’t accurate reflections of HTML5 capabilities.
