Which command sequence creates a new user with a home directory and adds it to the wheel group, then prompts to set a password?

• A. useradd -m -G wheel username; passwd username
• B. adduser username -m -G wheel
• C. useradd -d /home/username -G wheel
• D. createuser -m -G wheel username; passwd username

Answer: (A)

To create a new user with a home directory, put them in the wheel group, and then set a password, you rely on specific user management options: -m creates the home directory, and -G wheel adds the user to the wheel group. After the account is created, running passwd for that user prompts you to set their password. The sequence useradd -m -G wheel username; passwd username does exactly that: it ensures a home directory exists, grants wheel group membership (which on many systems enables sudo privileges), and then prompts for a password. The other options miss at least one requirement: one uses a nonstandard tool for Red Hat, another omits creating the home directory by not using -m with -d, and another uses a command not used for Linux user management.
