The correct option is B Monoculture in the area
Forests are made of different kinds of plants. They are composed of plants of different species. They show high biodiversity. Also, plants present in forests are naturally selected i.e., the plants which have highest possibility of survival. Depending upon the type of sand present in forest area, the plants are present. Each forest make a natural ecosystem in that region which is favorable for plant development.
Clearing such forests will demote biodiversity. It will destroy the natural ecosystem in that area. Such practices will promote monoculture in that area. Therefore, the correct answer is option B.
