Answer:
A, B, and D are the correct answers.
Explanation:
Trees must be cut down to make space available for the machinery required to excavate and extract minerals from the earth, and if the trees were not cut away, this process would be difficult in the limited space.
Roads and infrastructure must also be provided to that area so that road links are available, in order for the extracted minerals to be transported to processing zones or industries or the markets so that they can be sold.
D is also a valid answer as, in order for this to be a sustainable process, we must replant trees in another area so that there is no shortage of trees and so that land is reclaimed. Trees must also be planted in the area so that fresh air is provided to the miners who work inside the mines when they come out, and not polluted air. This also reduces the risk of various lung diseases affecting the miners such as Black Lung.
