Answer: Option (A) is the correct answer.
Step-by-step explanation:
Primary source of aluminium is it's ore, that is, bauxite. And bauxite is found in topsoil which is located in different parts of tropical and sub-tropical regions.
Therefore, mining of aluminium from new bauxite deposits will disrupt tropical rain forest animals as mainly we can find bauxite in tropical regions.
So, during mining of aluminium upon digging the ground will disturb the animal habitats and simultaneously it will affect their life.
Thus, we can conclude that a cost of mining aluminum from new bauxite deposits is disrupting tropical rain forest animals.
