Answer Details
In the upper course of a river, one can find features such as waterfalls, rapids, V-shaped valleys, interlocking spurs, and gorges, which are usually narrow and steep-sided. An ox-bow lake, on the other hand, is typically found in the lower course of a river where the river meanders and bends. Cataracts, meanwhile, are found in rivers that flow through rocky areas and can be found in both the upper and lower courses. Therefore, the correct answer is "ox-bow lake."
