Answer 1

The Correct Option is D

• A is incorrect: <a> mode is for writing; to read, <a+> is needed.
• B is correct: <a> will create the file if it doesn’t exist.
• C is correct: it writes only at the end.
• D is incorrect: 'r' is the default mode.
• E is correct: in append mode, writes occur at the file’s end.
