Matthew has embedded a video in his Web page using the HTML5 video format. The video is not rendering properly. He asks Arlene to help determine the problem, so she reviews his code, which appears as follows:

The ogg video format is not supported by HTML5. 

One of the video tag instances has not been properly closed. 

The browser plug-in information required to view the video is missing. 

The second instance of the <video> element should be replaced with the <source> element.
