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.

Explanation:
readline() method is used to read one line from a file. It returns that line from the file.
This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.
So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.
For example if the file "abc.txt" contains the lines:
Welcome to abc file.
This file is for demonstrating how read line works.
Consider the following code:
f = open("abc.txt", "r") #opens the file in read mode
print(f.readline()) # read one line from file and displays it
The output is:
Welcome to abc file.
The readline() method reads one line and the print method displays that line.
