Zimbabwe is a landlocked country in southern Africa lying wholly within the tropics. It straddles an extensive high inland plateau that drops northwards to the Zambezi valley where the border with Zambia is and similarly drops southwards to the Limpopo valley and the border with South Africa.
Zimbabwe does not border any large bodies of water.
It's definitely correct because it says it's a landlocked country, which means it cannot border any large bodies of water. This is difficult because the system might not really understand what it means for a country to be landlocked.
