MCQ Detailed View

To add audio or video files in an HTML document, the correct tag to use is the <embed> tag. This tag allows you to insert multimedia content such as audio, video, PDF, or Flash files directly into a webpage. The <embed> element is a general-purpose HTML tag used to include external resources and plugins within your content.

While the <audio> and <video> tags are also used in HTML5 to add audio and video files specifically, the <embed> tag provides broader compatibility and is often used for older formats or plugin-based media. It supports different file types and allows for flexible integration into websites.

For example, you can write the following code to embed a video:

<embed src="video.mp4" width="400" height="300">

In this example, the video file is displayed directly on the web page with the specified width and height.

Therefore, among all the given options, the <embed> tag is the most accurate answer, especially when referring to inserting both audio and video files using one tag.
