    Consider the following statements. I. \[{{C}_{4}}\] species have greater rate of \[C{{O}_{2}}\] assimilation than \[{{C}_{3}}\] species. II. \[C{{O}_{2}}\] compensation point is very high in \[{{C}_{4}}\] plants. III. The process of photorespiration involves the chloroplasts, peroxysomes and mitochondria. Which of the statements given above are correct?

    A)  I and II                        

    B)  I and III              

    C)  II and III                      

    D)  I, II and III

    Correct Answer: B

    Solution :

    \[C{{O}_{2}}\] compensation point is very low in \[{{\operatorname{C}}_{4}}-plan\] i.e., 0 to 5 ppm, whereas high \[C{{O}_{2}}\] compensate point is found in \[{{C}_{3}}-plants\] i.e., 25 to 100 ppm.
