Answer 1

Answer: (C)

$ C_{4} $ plants are characterised by Kranz type of anatomy i.e., chloroplast containing mesophyll cells and bundle sheath cells. The phosphoenol pyruvate in mesophyll cells combine with $ CO_{2} $ in presence of PEP carboxylase and forms oxalo acetic acid. The product of photosynthesis is starch.
