Options

AUsermod -sG wheel comptia
BUseradd -sG wheel comptia
Cvisudo -sG wheel comptia

Common mistakes.

A. The usermod command is used to modify an existing user account, not to create a new one. Additionally, the -s option is for setting the login shell, not for group assignment in this context.
C. The visudo command is used to safely edit the /etc/sudoers file to configure sudo privileges, but it does not add users to groups directly.
D. The sudo command is used to execute a command as another user (typically root) and is not used for managing user accounts or groups.
