If you want to append data to the existing binary file, BinaryFile.dat, use the following statements to open the file.
A) FileOutputStream fstream = new FileOutputStream("BinaryFile.dat");
DataOutputStream binaryOutputFile =
New DataOutputStream(fstream);
B) FileOutputStream fstream = new FileOutputStream("BinaryFile.dat", False);
DataOutputStream binaryOutputFile =
New DataOutputStream(fstream);
C) FileOutputStream fstream = new FileOutputStream("BinaryFile.dat", true);
DataOutputStream binaryOutputFile =
New DataOutputStream(fstream);
D) FileOutputStream fstream = new FileOutputStream("BinaryFile.dat");
DataOutputStream binaryOutputFile =
New DataOutputStream(fstream, true);

Option C is the best choice because it opens the file in append mode by specifying the "true" parameter in the constructor of FileOutputStream. This ensures that any data written to the file will be appended to the end of the existing data. Option A opens the file in write mode and overwrites any existing data, while Option B opens the file in write mode with the "false" parameter which is redundant because write mode is the default mode. Option D is not a valid syntax for creating a DataOutputStream object.
