Why have many countries in Southwest Asia had to develop new technologies such as d e s a l i n a t i o n in order to access freshwater aid because much of the region is mountains b because much of the region is covered in desert sea because the t i g r i s and EU p h r a t e s River no longer provide significant water flow D because much of South Asia is landlocked

The correct answer is B because much of the region is covered in desert. Southwest Asia is largely arid and experiences limited rainfall, making access to freshwater scarce. Countries in the region have had to develop new technologies like desalination to extract freshwater from the sea or other sources in order to meet the growing demand for water.
