Which security-related capability is provided by many operating systems?

• A. Provides automatic virus scanning.
• B. Allows creation and deletion of user accounts.
• C. Backups both system and user data.
• D. Sets display resolution.

Answer: (B)

Access control through user management is a security-related capability provided by many operating systems. By creating and deleting user accounts, the OS lets an administrator control who can access the system, what data they can see, and what actions they can perform. This helps enforce authentication and permissions, prevents unauthorized use, and supports accountability since each user’s actions can be tracked. Other options describe useful features, but they aren’t as universally tied to security as managing who can log in and what they’re allowed to do.
