Find the incorrect statement(s) about photosynthesis from the following :
A. The water splitting complex is associated with PS I.
B. $\text{C}_4$ plants use the $\text{C}_3$ pathway of $\text{CO}_2$ fixation as the main biosynthetic pathway.
C. In $\text{C}_4$ plants, photorespiration does not occur.
D. $\text{C}_3$ plants exhibit 'Kranz' anatomy.
E. ATP synthesis in chloroplast occurs through chemiosmosis.
Choose the answer from the options given below :

Statement A is incorrect because the water splitting complex is associated with PS II, not PS I.

Statement B is correct because the Calvin cycle ($\text{C}_3$ pathway) is the main biosynthetic pathway for all plants, including $\text{C}_4$ plants.

Statement C is correct because $\text{C}_4$ plants have a mechanism that increases the concentration of $\text{CO}_2$ at the enzyme site, preventing RuBisCO from acting as an oxygenase, thus avoiding photorespiration.

Statement D is incorrect because Kranz anatomy is a characteristic feature of $\text{C}_4$ plants, not $\text{C}_3$ plants.

Statement E is correct because ATP synthesis in chloroplasts is explained by the chemiosmotic hypothesis.

Therefore, the incorrect statements are A and D.

Answer: A and D only
