The myfile.readlines() function is used to read the entire files.
To get all the information in a file, readlines() is used. It returns the entire information in the file. The radlines() function gives all data in the file as a collection of strings. When using the readlines() function, all the data in the file is read and it will not be stopped until the entire file ends.

Assume that the position of the file pointer is at the beginning of 3r...
Explanation:
To read all the remaining lines in a text file, when the position of the file pointer is at the beginning of the 3rd line, you can use the `myfile.readlines()` option.
Here's a detailed explanation of the given options and why option 'D' is the correct answer:
a) myfile.read()
The `read()` function without any arguments reads the entire content of the file starting from the current position of the file pointer. However, in this scenario, it would only read from the current position to the end of the 3rd line, resulting in incomplete data.
b) myfile.read(n)
The `read(n)` function reads n characters from the file starting from the current position of the file pointer. It does not consider lines, so using this option would not guarantee reading the remaining lines properly.
c) myfile.readline()
The `readline()` function reads a single line from the file starting from the current position of the file pointer. If you repeatedly use this function, it would only read the next line each time, not all the remaining lines.
d) myfile.readlines()
The `readlines()` function reads all the remaining lines of the file starting from the current position of the file pointer. It returns a list where each element represents a line of the file. This option ensures that all the remaining lines are read properly.
In this scenario, since the file pointer is at the beginning of the 3rd line, using `myfile.readlines()` would read all the lines from the 3rd line to the end of the file, providing the desired result of reading all the remaining lines.
