Why each option
This question asks for the systemd equivalent of traditional runlevels in Linux.
"Services" are individual daemons or applications managed by systemd, not the collective states akin to runlevels.
In systemd-based Linux systems, the traditional SysVinit runlevels are replaced by 'targets.' Targets serve a similar purpose by grouping different services and units to bring the system to a specific operational state, such as multi-user, graphical, or rescue mode.
"Units" are the fundamental objects systemd manages (services, sockets, devices, mounts, etc.), and targets are a *type* of unit, but not the general term for runlevels.
"Modes" is a generic term and not the specific systemd terminology for runlevels.
Concept tested: systemd concepts (targets, runlevels)
