The correct option is C Kranz anatomy occurs where mesophyll have small chloroplasts whereas bundle sheath have larger, agranal chloroplasts
C4-plants have 'Kranz type' anatomy.
Vascular bundles are surrounded by bundle sheath cells.
The chloroplasts are dimorphic.
The cells of bundle sheath have very large chloroplasts. They lack grana and contain starch grains.
They are centripetally arranged while mesophyll cells have small and granal chloroplast.
