Consider the following water bodies : I. Lake Tanganyika II. Lake Tonlé Sap III. Patos Lagoon Through how many of them does the equator pass?

The correct answer is (D) because none of these water bodies intersect the equator: Lake Tanganyika lies entirely south of the equator in East Africa, Lake Tonlé Sap is located in Cambodia (Northern Hemisphere), and Patos Lagoon is situated in southern Brazil. Option (A) is the most tempting distractor because candidates often confuse Lake Tanganyika with Lake Victoria, which is the major African Great Lake actually bisected by the equator. The core concept tested is the spatial relationship between significant global geographical features and primary latitudes.
