What tool can be used to manage user accounts and groups in Linux?

The toolset that includes useradd, usermod, and userdel is specifically designed for managing user accounts and groups within a Linux environment.

The useradd command is utilized to create new user accounts, providing options to set important parameters such as home directories and default shells. usermod is intended for modifying existing user accounts, allowing administrators to change settings such as group memberships, usernames, and other user attributes. Finally, userdel is used to remove user accounts from the system.

These commands are essential for effective user management and are standard across various Linux distributions, making them versatile and widely applicable.

While other choices might contain commands that sound related, they either do not exist as standard tools for user and group management or lack full functionality. For instance, adduser is sometimes a synonym for useradd on certain distributions, but it does not provide the comprehensive suite that option A does. Other mentioned commands do not align with standard names or functionalities for managing users and groups effectively.
