Final answer:
AppendMode is generally used with text files to add new data without overwriting existing content. It can be used with output files but is not suitable for input files intended for reading. While it is less common, append mode can also be applied to binary files with caution. The correct answer is option A. Text file
Step-by-step explanation:
The AppendMode is typically associated with text files (A). When you open a file in append mode, the goal is to add more data to the existing content of the file without overwriting it. This mode is quite useful when you have a log file or any other type of information journaling where you want to keep a record of events, inputs, or changes over time.
Append mode can also be used in other contexts like output files where you're writing data, but it's important to distinguish that append mode is not applicable for input files since input mode is used for reading, not writing. Moreover, while append mode can be used with binary files, this is less common as binary files often contain structured data where appending might disrupt the structure.
In programming languages like Python, Java, and C++, the append mode is invoked by specifying a specific mode (such as 'a' or 'ab' for appending to binary files) when opening a file. Carrying out file operations with the correct mode ensures that the file's contents are not accidentally deleted or corrupted.
