Of the given video file extensions, which was developed by Microsoft?

.mp4
.mov
.avi
.mkv

The correct answer is: .avi

The video file extension that was developed by Microsoft is .avi, which stands for Audio Video Interleave. This format was introduced in November 1992 as part of Microsoft's Video for Windows technology. The .avi format allows for the simultaneous playback of audio and video, making it a popular choice for multimedia files during its early days. It supports multiple streams of audio and video, which can enhance the viewing experience. In contrast, other file extensions listed, such as .mp4 and .mov, were developed by different organizations; .mp4 is associated with the Moving Picture Experts Group (MPEG), and .mov was developed by Apple for its QuickTime framework. The .mkv format, known as Matroska video, is an open-standard container format created independently to support various codecs and subtitles. Thus, .avi is distinctly recognized as Microsoft's development in the realm of video file formats.
