B Correct answer
Explanation

The @COPY,A command copies an absolute file (creating a new copy), while @ASG,A assigns an already existing symbolic file (creating a reference or alias). The 'A' suffix in @COPY,A indicates it works with absolute files, which have actual data allocated. The @ASG with symbolic files creates pointers rather than full copies. The other combinations mix up absolute/symbolic incorrectly.
