Answer:
A. The song was saved using fewer bits per second than the original song.
Explanation:
A song can be recorded on the computer or any device ranging from bit rates 96 kbps to 320 kbps.
The lesser the bitrates the lesser the quality of the audio and when we increase the bit rates, the quality of the audio recorded gradually increases.
Bitrates of 128 kbps give us a radio like quality whereas when we use bitrates of 320 kbps we get very good or CD-like quality.
According to the scenario, the most appropriate answer is option A.
