The correct answer is option 4, Africa. This is because Africa is the only continent through which all three latitudes pass. The equator is an imaginary line that divides the Earth into the Northern Hemisphere and Southern Hemisphere, and it passes through several countries in Africa, including Kenya, Uganda, and Gabon. The Tropic of Cancer is located at approximately 23.5 degrees north of the equator, and it passes through the northern regions of Africa, such as Algeria, Egypt, and Mauritania. The Tropic of Capricorn is located at approximately 23.5 degrees south of the equator, and it passes through southern African countries like Namibia, Botswana, and Mozambique. Therefore, Africa is the only continent where all three latitudes intersect.
