Answer:
Option (A)
Step-by-step explanation:
Deforestation process describes the cutting down of trees or wiping out of forest areas. It is done so in order to construct building, houses, and other commercial buildings, expansion of agricultural fields, extraction of woods. It mostly takes place in the tropical region in which the number of plants and trees are significantly very high.
Desertification is defined as the process by which a fertile land degrades and become infertile. It is caused due to the rapid soil erosion process, deforestation process and also due to drought.
These two processes are directly related to one another. It is because when deforestation takes places, there results in the process of desertification as the fertility of the land (soil) is reduced to a large extent. And due to this, the organisms living in that particular places loses their habitat and also the land is no more suitable for growing any kinds of crops.
Thus, example A shows the correct relationship, i.e. the cause and effect of one another.
Hence, the correct answer is option (A).
