To analyze the question, we need to identify the rivers based on their locations relative to the countries mentioned.
River A is near the Democratic Republic of the Congo, which is most likely the Congo River, as it is the major river in that region.
River B is near Zambia and Zimbabwe, which indicates it is likely the Zambezi River, as it flows through both countries.
With this information, we can conclude:
- River A is the Congo River.
- River B is the Zambezi River.
Thus, the correct answer is:
C. Congo . . . Zambezi
