   • BRead the CSV and create all users with useradd, but do not set passwords or force password change.
   • CUse newusers to create all users from the CSV, but do not handle duplicates or force password change.
   • DRead the CSV line by line, check if the username exists with id, if not create the user with useradd and set the password with chpasswd, then use chage -d 0 to force password change.

   An IT administrator is writing a bash script to onboard new employees. The script must create a user account for each employee, add the user to a specific group, and create a home directory with a default set of files. The script should also ensure that if the user already exists, it does not fail but simply skips to the next user. Which script logic best achieves this?

   • AUse useradd with the -m flag to create the home directory, then use usermod -aG to add the group, and check if the user exists with id before creating.
   • BUse useradd without the -m flag, then manually create the home directory with mkdir, and add the group with usermod -G.
   • CUse a loop that reads employee names, but only creates the user with useradd and does not add to any group.
   • DUse adduser with the --home flag, then use gpasswd to add the group, and do not check if the user already exists.
