Which of the following file formats are appropriate for distributing video files across the internet?

The FLA and AVI formats are the video related choices here, which are Statements 1 and 5.

Statement 1, FLA, is the Adobe Flash format tied to animated and video content for the web.

Statement 5, AVI, is a common video container that holds moving images with sound.

Statement 2, MP3, is an audio format for compressed music, not video.

Statements 3 and 4, WMA and AIF, are also audio formats and carry sound only.

Distributing video means choosing a format that stores moving pictures, unlike the audio only types.
