Correct answer: B
CONCEPT
A file format is classified by the kind of information it represents, not merely by whether it can contain an audio track. An audio-oriented format stores encoded sound or musical-performance data, whereas a video or multimedia container can combine moving pictures with sound.
APPLICATION
Classify each listed format by its designed payload before comparing the offered pairs.
Format | Designed payload |
|---|---|
AVI | An Audio Video Interleave container that synchronizes moving pictures and sound. |
MIDI | Musical-performance instructions such as notes, timing, and instruments for sound synthesis. |
WMV | Windows Media Video content, ordinarily carrying moving images and associated audio. |
WMA | Windows Media Audio, designed for compressed audio streams. |
MP4 | A multimedia container that can carry video, audio, subtitles, and related data. |
CONTRAST
AVI and WMV both include a moving-image role.
MIDI is paired with MP4, whose payload may include video and other media.
WMV contributes moving-image content even though WMA is audio-oriented.
CROSS-CHECK
The expanded names confirm the distinction: Audio Video Interleave and Windows Media Video are not sound-only formats, while Musical Instrument Digital Interface and Windows Media Audio are sound-oriented.
Therefore, the pair containing exclusively sound-oriented formats is MIDI and WMA.
