Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In Python, the "a" mode opens a file for appending, and "w" mode opens a file for writing. "r" is for reading. The "ab" mode is valid only for binary files, not for text files. Therefore, the correct answer is "ab" for text files.
