Option A uses the FileWriter constructor with the boolean "append" parameter set to true. This ensures that the existing contents of the file are not overwritten when appending new data. Option B creates a FileWriter object without the "append" parameter, so the existing contents will be overwritten. Option C creates a PrintWriter object with the "append" parameter, but without setting up a FileWriter object first. Option D creates a PrintWriter object with the wrong parameter order and would result in a syntax error.
