-
A.
MPEG-1 Layer II audio
chosen
MPEG-1 Layer II audio is a lossy audio compression format widely used in digital broadcasting and early digital media for efficient, good-quality stereo sound.
-
B.
MPEG-2 AAC
MPEG-2 AAC is an advanced audio coding standard that provides higher compression efficiency and better sound quality than earlier MPEG audio formats, and is widely used in digital broadcasting and multimedia applications.
-
C.
MPEG-1 Audio Layer III
MPEG-1 Audio Layer III, commonly known as MP3, is a widely used digital audio encoding format that compresses sound data to significantly reduce file size while maintaining acceptable sound quality.
-
D.
MPEG-4 Part 2
MPEG-4 Part 2 is a video compression standard used for encoding digital video, notably in early MPEG-4 and DivX/Xvid formats.
-
E.
HE-AAC v2
HE-AAC v2 is an advanced audio codec profile that combines AAC with spectral band replication and parametric stereo to deliver high-quality sound at very low bitrates, commonly used in streaming and broadcasting.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
