Question

what attribute tells the browser how long a video will run? a the length attribute tells the browser how long a video will run. b the loop attribute tells the browser how long a video will run. c the controls attribute tells the browser how long a video will run. d there is no attribute that tells the browser how long a video will run.

Explanation:

• Option A: There is no "length" attribute in HTML for the <video> tag to specify video duration.
• Option B: The "loop" attribute is for making the video play repeatedly, not for indicating duration.
• Option C: The "controls" attribute is for displaying playback controls (like play, pause, volume), not for duration.
• Option D: The browser determines the video's duration from the video file itself, and there's no HTML attribute that explicitly tells the browser the video's runtime; the browser parses the video metadata to get duration.

Answer:

D. There is no attribute that tells the browser how long a video will run.
