A. write mode
B. read mode
C. append mode
D. Both (A) And (B)

Solution

A. write mode

Explanation

In Python, the "w" (write) mode is used to open a file for writing. If the file specified in the open function does not exist, it will create a new file. If the file already exists, opening it in write mode will truncate the file to zero length, effectively erasing its content.
