1.Moving Pictures Experts Group Layer 4 (.mp4)

2..mp3

3..rar

4..zip

A3 & 4 only

B2, 3 & 4 only

C1, 3 & 4 only ✓ Correct

D1, 2, 3 & 4

Correct answer: (C) 1, 3 & 4 only

Explanation

Statement 1, the mp4 file, is a container able to bundle video, audio, subtitles and metadata together.

Statement 3, a RAR archive, packages many files of any type into one compressed container.

Statement 4, a ZIP archive, likewise wraps multiple mixed files into a single compressed container.

Statement 2, an mp3 file, is a single audio stream and not a multi-type container.

This makes the mp4, RAR and ZIP the three container formats among the four.

A container format defines only how data streams are stored, independent of the codecs used.
