Explanation

'vgchange -ay data' activates all logical volumes within the volume group named 'data' (the '-a y' flag means 'set active to yes'). During maintenance, volume groups are commonly deactivated so the disk can be safely manipulated. Without the volume group being active, its logical volumes are unavailable and cannot be mounted. Option B (lvscan --all) only scans and lists LVs without activating them. Option C (vgimport) is used when moving a VG from another system that was previously exported with 'vgexport'. Option D (lvchange -ay) activates a single LV rather than the entire VG, which may be insufficient if the VG itself is inactive.
