The correct answer for above statement is:
D.Forests prevent desertification.
Step-by-step explanation:
Forests and deserts are associated because many survive in close vicinity to one another: a desert that gets adequate rainfall to plant trees can change into a forest, while a forest that undergoes dehydration may notice fast desertification. Forests are a way of stopping the extent of deserts since some trees can grow in areas with limited rainfall and stop soil erosion.
