Examine the output of the command:

Which two statements are true? (Choose two.)

A. The names in the first column represent only cgroup subsystems that are currently attached to any cgroup hierarchy regardless of whether they are mounted or unmounted.

B. cpuset, cpu, memory, cpuacct, and blkio are cgroup subsystems and they are attached to mounted cgroup hierarchies. The numbers in the second column represents the number of cgroups to which corresponding subsystems are attached.

C. cpuset, cpu, memory, cpuacct, and blkio are cgroup subsystems and they are attached to mounted cgroup hierarchies. The numbers in the second column represents arbitrary system-assigned cgroup hierarchy numbers.

D. cpuset, cpu, memory, cpuacct, and blkio are cgroup subsystems and they are attached to mounted cgroup hierarchies. The numbers in the second column represents the number of cgroups in each cgroup hierarchy.

E. The names in the forst column represent all cgroup subsystems available on the system.
