Joe, a technician, is using a terminal session on a Linux desktop. He is trying to install a software update but receives an error message stating he does not have the required privileges. Which of…

pwd (print working directory) displays the current directory path and has no effect on user privileges.

apt-get is the package management command used for installation, but it does not grant privileges - it still requires sudo to run with the necessary permissions.

chmod modifies file or directory permissions, not the current user's privileges for executing a command.

sudo (superuser do) temporarily grants root-level privileges to the invoking user for a single command, which is the correct way to run privileged operations like software installation in Linux. Prepending sudo to the apt-get command would resolve the privileges error without requiring a full root login.
