Explanation

Two issues must be fixed: (1) The script is missing a shebang line at the very top. A shebang (e.g., #!/bin/bash) must be the first line of the script - it tells the kernel which interpreter to use. Option A is wrong because placing it at the bottom does nothing; Option C correctly places the shebang at the top (the double slash in '#!//bin/bash' is a typo in the question but the intent is the correct first-line shebang). (2) To run the script as a service at startup under systemd, a unit file must be created in /etc/systemd/system/ with a .service extension (Option B). Option E is incorrect because /etc/init.d/ is the legacy SysV init directory, not used by modern systemd-based systems. Restarting or shutting down the computer (D, F) is not a fix for either issue.
