Installing the application 'nano' in Linux typically depends on the package management system of the distribution you are using. The command provided as the answer, "apt-get install nano," is correct for systems that use the Advanced Package Tool (APT), such as Debian-based distributions like Ubuntu. This command facilitates the installation of the nano text editor through the package repository, automatically managing dependencies and ensuring that the software is correctly set up on the system.

The other options refer to different package management systems. "yum install nano" is used for Yellowdog Updater Modified, which is associated with Red Hat-based distributions like CentOS. "rpm install nano" pertains to the RPM Package Manager, which is also used in Red Hat-based distributions but requires the RPM file directly. "dpkg install nano" is a command for Debian-based systems but is less commonly used directly since APT is preferred for package installations as it handles dependencies.
