Which one of the following countries is located south of the equator?

The equator (0° latitude) divides the Earth into the Northern and Southern Hemispheres [1]. In Africa, the equator passes through Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, and Somalia [t1][t2]. Countries located north of this line are in the Northern Hemisphere, while those to the south are in the Southern Hemisphere. Cameroon, Sudan, and Nigeria are all located entirely in the Northern Hemisphere, with their territories situated north of the equator. Rwanda, however, is located just south of the equator, with its northern border situated at approximately 1°S latitude. While some countries like Uganda and Kenya are crossed by the equator [t1], Rwanda lies completely within the Southern Hemisphere, making it the correct choice among the provided options.
