Detailed Solution

Let's go over the choices and talk about the solution.
Choice 1. The Great Escarpment, which rises to a height of 790 meters, distinguishes the eastern edge of the Brazilian Highlands. The Escarpment serves as a barrier against the Southeast trade winds and produces orographic precipitation near the beach. Beyond the highlands, these breezes have less of an influence, resulting in minimal precipitation. In the northeastern corner of the ledge, a rain shadow area develops. As a result, it is the best choice.
Options 2. The Brazilian Highlands are a significant aspect of Brazil. It is where the nation's mineral wealth is found. It also goes by the name Brazilian Plateau. The trade winds are not prevented by it. As a result, it is the wrong choice.
Option 3: The Pampas or Brazilian plains are the nation's most productive land. The nation's breadbasket is there. Given that it is a low-lying region, it plays no role in serving as a barrier. As a result, it is the wrong choice.
Option 4: Brazil is surrounded by a number of islands. They are located east of the large escarpment and lack any mountains that rise higher than it. Consequently, they are not a barrier. As a result, it is the wrong choice.
