The ‘lsvg -o’ command is run with an output of only rootvg， but the server has another volume group named datavg， which is not displayed. What is the likely cause？（）

• A、datavg is in an offline state.
• B、‘lsvg -o’ only displays the root volume group.
• C、‘lsvg -o’ only displays the fist volume group.
• D、datavg has no filesystems and therefore， is inactive.
