Explanation

The equator (0° latitude) is an imaginary line that divides the Earth into the Northern and Southern Hemispheres. For the equator to pass through a water body, that body must be located precisely at or straddling 0° latitude.

Lake Tanganyika is located in central-eastern Africa, bordering Tanzania, the Democratic Republic of Congo, Burundi, and Zambia. It is one of the deepest and oldest freshwater lakes in the world. Despite being in central Africa — a region associated with the equator — Lake Tanganyika lies entirely south of the equator. The equator passes to its north, not through it. ❌

Lake Tonlé Sap is the largest freshwater lake in Cambodia, located in the central plains of Southeast Asia. Cambodia lies entirely in the Northern Hemisphere, and Lake Tonlé Sap sits at approximately 13° North latitude — well north of the equator. ❌

Patos Lagoon (Lagoa dos Patos) is one of the largest coastal lagoons in South America, located in the southern part of Brazil near the Atlantic coast. It sits at approximately 30° South latitude — far south of the equator. ❌

Since none of the three water bodies are intersected by the equator, the correct answer is None.
