Answer:
D) use of the Rio de la Plata
Step-by-step explanation:
Uraguay and Paraguay are two nations located in South America, and they have lot of similarities between them. One big difference though is that Uruguay is coming out on ocean waters, while Paraguay is landlocked. Uruguay uses the Rio de la Plata as the most important place for its ports, thus for trading globally, while Paraguay is not able to do so as it doesn't have access to the Rio de la Plata.
