In the question "Continued deforestation will most likely lead to _______." the correct answer is "an increase in the number of endangered species" (option b).
Deforestation is the clearing of forest areas for use for non forest activities. Because there are a lot of animals that use forests as their home, clearing of the forest will make them homeless and will subject them to conditions that may lead to their death and possible extinction.
