Explanation

Option A correctly pairs MP4 and OGG sources, which together cover the two major browser camps - MP4 for Chrome, Safari, and IE/Edge; OGG for Firefox and Opera. This two-format combination was the established standard for maximum HTML5 video compatibility.

Why the distractors fail:

• B and C both use the filename extension .web instead of the correct .webm, creating a mismatch between the filename and the declared MIME type video/webm - the browser would fail to load those files.
• D includes a correct .webm source but adds a third format, making it redundant; MP4 already covers the browsers that WebM targets, so the extra source adds no meaningful compatibility benefit and the exam expects the clean two-source standard.

Memory tip: Think "MP4 + OGG = covered" - MP4 handles the WebKit/Blink world, OGG handles the Gecko world. If you see .web as a filename extension anywhere in an answer, eliminate it immediately - the correct extension is always .webm.
