The correct answer is: thick walls, no intercellular spaces and large number of chloroplasts
$\mathrm{C}_4$ plants have a characteristic leaf anatomy, called 'Kranz' anatomy. Kranz means 'wreath' (ring) and is a reflection of the arrangement of cells. The large sized bundle sheath cells may form several layers around the vascular bundles. These cells are characterised by having a large number of agranal chloroplasts, thick walls impervious to gaseous exchange and no intercellular spaces.
