As the Climate Warms, the Population Ranges of Organisms May

As the climate warms, the population ranges of organisms may shift to different areas that are cooler. However, as humans continue to fragment large tracts of land, species will face increasing challenges in adapting their ranges to new climates. For example, movement corridors may not be able to be built if the amount of land needed for a species' range is fragmented due to cities and roads. One alternative to creating movement corridors is called managed relocation. This requires physically moving species to cooler climates.
-What is an advantage of using managed relocation?

A) Scientists will be able to accurately predict how many members of a species will survive the relocation because they can start the process with a definite number of members being moved.
B) Purposefully moving species will allow scientists to put specific numbers of organisms in different areas so that the species population always maintains an even distribution of organisms across the area.
C) All species moved will be saved from extinction.
D) Governments will not face the large costs of maintaining conserved areas for corridors.
