The 'lsvg -o' command is run with an output of only rootvg, but the server has another volume group named datavg, which is notdisplayed. What is the likely cause?（）
- Adatavg is in an offline state.
- B'lsvg -o' only displays the root volume group.
- C'lsvg -o' only displays the fist volume group.
- Ddatavg has no filesystems and therefore, is inactive.
