D is correct. check the following link: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/managing_software_with_the_dnf_tool/assembly_handling-package-management-history_managing-software-with-the-dnf-tool#:~:text=Reverting%20transactions%201%20To%20revert%20a%20particular%20transaction%2C,last%20transaction%2C%20use%3A%20%23%20dnf%20history%20undo%20last

D. dnf history and dnf history undo last The "dnf history" command displays the history of all transactions performed using the DNF package manager, including package installs, upgrades, and removals. The "dnf history undo last" command undoes the last transaction, effectively removing the package that was installed. By using these two commands, the systems administrator can reveal the system to a compliant state by removing the unapproved packages. Option A "dnf list and dnf remove last" lists the packages installed on the system, but it does not undo the last transaction. The "dnf remove last" command is not a valid command.

Yeah D is the correct answer. If there were multiple unwanted changes, the admin could also run the “rollback” option instead of “last”

D is wrong, the right answer is A
