The correct answers are "Animals will migrate to other regions in search of food" & "The new species will evolve to survive in the deforested land".
Whenever an area in a forest is cleared up to build a road or because of any other reason the habitat of the animals residing there is destroyed. So, in search of food and alternate habitat the animals start to migrate to other nearby regions. The destruction of the natural habitat will lead to the accumulation of new traits in the species which are left in the forest leading to the evolution of new species which are well fitted to live in the new environment.
Rest of the options are wrong because if the forest area will be cleared then it will lead to the decrement of trees not increase. Also, adapting the changing environment is a long term change but here they are saying the animals will immediately adapt to the new environment so this option is also wrong.
