Correct Answer Explanation:
MS-DOS (Microsoft Disk Operating System) is a single-user Operating System. Only one user can log in and operate it at a time, and it can only run one program at a time (single-tasking).
Why the other options are incorrect:
- Option A: MS-DOS was not designed for multiple users — it lacks the account and permission systems needed for multi-user support.
- Option C: MS-DOS has no built-in networking capabilities that would make it a Network OS.
- Option D: MS-DOS runs on a single standalone PC and cannot distribute tasks across multiple computers.
