D is absolutely correct since every other choice only has "%100" instead of the proper format, "%100FREE". lvextend and lvresize can both be used, even with -l from there.

Selected Answer: D

lvextend or lvresize could both get the job done here. The key here is "-r", resize the associated filesystem.

lvresize -l100%FREE -r /dev/mapper/linux-root Explanation: -l // [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] eg. "-l +100%FREE" -r // Resize underlying filesystem together with the logical volume using fsadm
