Final answer:
Africa’s savannas are suitable for raising herds of animals option (b) due to their expansive grasslands, hot climate, and seasonal rainfall patterns.
Step-by-step explanation:
Africa’s savannas are expansive grasslands with scattered trees and are particularly well-suited for raising herds of animals. They cover a significant portion of the continent and feature a climate that is wetter than the desert but drier than the rainforest.
The climate conditions in savannas include hot temperatures and a long dry season, along with seasonal rainfall which can be quite abundant in some areas. Animal migrations, like those in the Serengeti, are a notable feature due to the seasonal availability of water and food.
While the soil in savanna areas is generally not as productive for crops due to variable precipitation, livestock grazing is prevalent, and cattle migration follows seasonal conditions.
