A2 & 3 only

B2 & 5 only ✓ Correct

C1 & 4 only

D1 & 5 only

Correct answer: (B) 2 & 5 only

Explanation

WAV and MP3 are purely sound formats suited to the web, which are Statements 2 and 5.

Statement 2, WAV, stores audio, though its large uncompressed files suit short clips online.

Statement 5, MP3, is a compressed audio format ideal for streaming and downloading music.

Statement 1, WMV, is a Windows video format, not a sound only format.

Statements 3 and 4, AVI and MOV, are container formats that carry video, not audio alone.

A sound only file holds just an audio track, unlike a video container that also holds images.
