Choose the correct answer from the options given below:

The correct answer is (A) and (E) only.

To understand why these formats are appropriate for distributing video files, we can analyze each of the given options:

1. FLA (represented by A):
FLA is the project file format created by Adobe Animate (formerly Adobe Flash Professional). Historically, Flash technology (specifically via SWF and FLA files) was one of the most widely used methods for creating, playing, and distributing interactive vector graphics, animations, and video streams across the web.

2. .MPS (represented by B):
This is not a standard video distribution file format.

3. .WMA (represented by C):
Windows Media Audio (WMA) is an audio data compression technology and file format developed by Microsoft. It is strictly an audio format, not a video format.

4. AIF (represented by D):
Audio Interchange File Format (AIFF or AIF) is a standard audio file format used for storing sound data for personal computers and other electronic audio devices. It does not contain video data.

5. AVI (represented by E):
Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft. It contains both audio and video data in a file container that allows synchronous audio-with-video playback, making it a standard format for distributing video files.

Therefore, among the options provided, only FLA (A) and AVI (E) are associated with the distribution of video/animation files across the internet.
