Which one among the following is not a landlocked country in Africa ?

Africa contains 16 landlocked countries, the highest number of any continent. Botswana is a landlocked state in Southern Africa, bordered by Namibia, South Africa, Zambia, and Zimbabwe. Zambia is also landlocked, situated in the interior and historically linked to coastal ports like Dar-es-Salaam via the Tanzania Railway [2]. Lesotho is a unique landlocked country as it is an enclave entirely surrounded by the territory of South Africa [2]. In contrast, Nigeria is a littoral country located in West Africa with a significant coastline along the Gulf of Guinea in the Atlantic Ocean [3]. Nigeria's railway network connects its interior centers directly to its port cities, facilitating maritime trade that landlocked neighbors lack [1]. Therefore, Nigeria is the only country among the options that is not landlocked.
