Option A. shutdown -r now and Option C. telinit 6 reboot the system when using SysV init.
Option A: The shutdown -r now command reboots the system when using SysV init. It sends a signal to init to switch to runlevel 6, which is the runlevel used to reboot the system.
Option B: The shutdown -r "rebooting" command does not reboot the system. The -r option tells shutdown to reboot the system, but the command must also specify a time at which the reboot should occur.
Option C: The telinit 6 command tells init to switch to runlevel 6, which is the runlevel used to reboot the system when using SysV init.
Option D: The telinit 0 command tells init to switch to runlevel 0, which is the runlevel used to halt the system. It does not reboot the system.
Option E: The shutdown -k now "rebooting" command does not reboot the system. The -k option tells shutdown to send a warning message to all logged-in users, but it does not initiate a reboot.
