Answer
Option (a) is the correct answer.The greatest threat to the wet tropical forests of Central America is due to the habitat destruction of these forests through clearance of forest lands for the purpose of coffee plantation.
Work Step by Step
Degradation of the forests created the ecological issues in every area of the world. Deforestation is taking place at a rapid pace and mostly in the tropical regions where large pieces of land are cleared out every year for a new plantation. The monetary benefit associated with the coffee plantation is the major reason for the large-scale clearance of forest lands of wet tropical forests of Central America. This leads to habitat destruction and a consequent species loss. Hence, option (a) is correct.
