Read the given statements and select the correct option.
Statement 1 : To maintain soil fertility, it is essential to prevent overgrazing and deforestation.
Statement 2 : Roots of plants grasp soil well and prevent removal of top soil by air, water, etc.

A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true and statement 2 is false.
D Both statements 1 and 2 are false.


Please see to it that you may have typed the word "fertility" instead on the word "erosion". Soil grasping has nothing to do with soil fertility.
