Productivity is defined as total production per hectare.
Total productivity of pulses in the year 2006
Total productivity of pulses in the year 2007
Total productivity of pulses in the year 2008
We can see that clearly, Total productivity of pulses in the year 2008 > Total productivity of pulses in the year 2007>Total productivity of pulses in the year 2006. Hence, statement I is incorrect. Hence, we can reject option A and B.
Productivity of Maize in the year 2006
==1.097Productivity of Maize in the year 2007
==1.094Productivity of Maize in the year 2008
==1.073We can see that productivity is approximately same during the given period for Maize. Hence, statement II is correct.
Therefore, we can reject option D.
Thus, we can say that option C is the correct answer.
