Correct Answer

Correct Answer Explanation:

A single-user OS supports only one user at a time. All resources are dedicated to that user, and no simultaneous logins are possible.

Why the other options are incorrect:

Option A: Many users at once would be a Multi-User OS, not Single-User.
Option C: No user is not possible — someone has to operate the system.
Option D: Guest support is just an account type; the classification is by number of concurrent users, not user type.
