The statement that best describes why southwest South America has a dry climate is:

There is a cold ocean current on the west coast of South America.

This refers to the Humboldt Current, which is a cold ocean current that flows northward along the coast of Peru and Chile, contributing to the aridity of the region by cool air and reducing evaporation rates, which in turn leads to less precipitation.
