Southwest asia and north africa often receive water from sources outside the region. which of the following statements is not true?

a. the tigris-euphrates river is fed by snowmelt of the mountains in turkey and iran.
b. the nile river is fed by the equatorial area around lake victoria.
c. the nile river is fed by seasonal rainy area of the ethiopian highlands.
d. the tigris-euphrates river is fed by seasonal rainy area of the ethiopian highlands.

The correct answer is - D. The Tigris-Euphrates River is fed by seasonal rainy area of the Ethiopian Highlands.

The Tigris-Euphrates Rivers are exclusively Asian rivers and they do not have any point that passes through the African continent, or in this case more specifically the Ethiopian Highlands in East Africa. Both Tigris and Euphrates are rivers that start their flows from the highlands in Turkey and Iran, and the main contributor to their water flows are the melting snows from the high mountains in these parts, and the occasional rains that appear there.
