   A Python script uses the multiprocessing module. When packaged with PyInstaller on Windows, the resulting executable crashes on startup. What is the most likely cause and solution?

   • AThe executable was built with --onefile; use --onedir instead.
   • BThe script uses a relative path that does not exist in the frozen environment; use an absolute path.
   • CThe script lacks a freeze_support() call; add it inside the if __name__ == '__main__' block.
   • DThe script uses too many processes; reduce the number of processes.
