To append data to an existing file, we typically use the File.AppendText method. This method opens the file if it exists and seeks to the end of the file, and if the file does not exist, it creates a new file. Using File.AppendText ensures that the new data will be added to the end of the existing file without overwriting or deleting any existing data. Therefore, the best choice is C - File.AppendText.
