The correct answer is - B. Roman Catholicism.
The Spanish people, with their arrival and settling in Latin America, brought with them their culture as well, and one big part of their culture was their religion. They were practicing the Roman Catholicism, and still are, being one of the ''biggest believers'' in the Christian faith nowadays.
The Spanish encountered multiple civilizations in this region, and after they conquered them, they started to assimilate them, some of which forcefully. Over time, their assimilation turned out to be a success, so the most dominant religion, by far, in Latin America is the Roman Catholicism.
The appropriate response is Oasis. It is shaped from underground streams or aquifers, for example, an artesian aquifer, where water can achieve the surface normally by weight or by man-made wells. Periodic brief rainstorms give underground water to manage common desert gardens, for example, the Tuat. Substrata of impermeable shake and stone can trap water and hold it in pockets, or on long blaming subsurface edges or volcanic barriers water can gather and permeate to the surface.
