all of the above


Please select the best answer from the choices provided

A
B

D

Answer 1

A

Deforestation removes protective vegetation and soil cover, increasing erosion and reducing moisture retention — which, combined with drought, commonly leads to desertification. (B is wrong because "sustainable" grazing prevents degradation; C can contribute in some cases, but A is the best single answer.)
