To determine which waterform is not identified correctly, let's analyze the descriptions given for each letter in relation to their geographic locations:
A. Letter A -- Congo River: This river flows through the Democratic Republic of the Congo, which is correct.
B. Letter B -- Zambezi River: This river flows between Zambia and Zimbabwe, which is also correct.
C. Letter C -- Lake Malawi: This lake is indeed located near Malawi, which is accurate.
D. Letter D -- Lake Tanganyika: This lake is primarily located between Uganda and Tanzania (with a portion touching Burundi and the Democratic Republic of the Congo), but it is not near Kenya.
Therefore, the waterform identified with "D" is not correctly positioned as described due to its geographic associations. The correct identification for Lake D should not include Kenya.
The best answer is:
D
