Which one of the following countries is land locked?

Bolivia is the correct answer because it is one of the two landlocked countries in South America, the other being Paraguay. Unlike the other options provided, Bolivia has no direct access to an ocean. Peru is located on the western coast of South America and has an extensive coastline along the Pacific Ocean. Suriname is located on the northeastern coast of the continent and borders the Atlantic Ocean. Uruguay is situated on the southeastern coast and also has a coastline along the Atlantic Ocean. Historically, Bolivia did have a coastline, but it lost its access to the sea to Chile during the War of the Pacific in the late 19th century. Since then, it has remained landlocked.
