One of the most crucial aspects in determining global climate patterns is latitude. Temperatures are lowest at higher latitudes, such as in the world's polar regions. Because of the earth's curvature, temperatures decline as one moves further from the equator.
The same types of biomes tend to occur at similar latitudes across the globe, according to the link between latitude and biomes. Each biome has its own set of climatic conditions, but in this case, the environmental condition is determined by latitude.
As a result, Option (c) is the proper response.
