Which of the following apt-get commands will install the newest versions of all currently installed packages?
Correct Answer: B
Explanation
The apt-get command is used to interact with the APT package management system on Debian-based Linux distributions. The apt-get command has several subcommands that perform different operations on packages.
One of these subcommands is full-upgrade, which is used to install the newest versions of all currently installed packages, along with their dependencies. The full-upgrade command also removes any packages that are no longer needed or that conflict with the upgraded packages. The full-upgrade command is equivalent to the dist-upgrade command, which is an older name for the same operation. The other options are not valid subcommands of apt-get. The auto-update option does not exist, the install option is used to install specific packages, not to upgrade them, the update option is used to update the list of available packages, not to install them, and the dist-upgrade option is the same as the full-upgrade option.
