What command is used to remove a previously added PPA in Linux?

The command to remove a previously added Personal Package Archive (PPA) in Linux is indeed represented by the option providing the syntax add-apt-repository --remove ppa:PPA_Name/ppa. This command is part of the add-apt-repository utility, which is used to manage PPAs on systems that utilize the APT package management system.

Using the --remove option directly specifies that you want to delete the specified PPA. This approach ensures that the package source associated with the PPA is removed from your system's package management configuration, thereby preventing the system from checking that PPA for updates or packages in the future.

The syntax also has the benefit of being user-friendly, as it aligns with the way PPAs are typically added. When adding a PPA, the command also uses add-apt-repository, making it consistent and easier to remember.

In contrast, other options are either not valid commands or do not follow the correct syntax for removing a PPA specifically, further emphasizing why the option that includes the --remove flag is the correct choice.
