Why each option
The .mp4 file extension is widely recognized as a standard format for digital video, making it the identifier for a video file among the given options. This container format can hold video, audio, and other data.
.msi (Microsoft Installer) is an installation package file used by Windows to install or uninstall software.
.tar (Tape Archive) is an archiving file format used to collect multiple files into one, typically for backup or distribution, not a video file.
.img (Image) can refer to several types of image files, including disk images or raw image data, but not typically a standard video file.
The .mp4 extension identifies a video file, as it is a common container format for multimedia, primarily used for storing digital video and digital audio streams. MP4 is based on the Apple QuickTime file format and is widely supported across devices and platforms.
