Final answer:
Africa is rich in natural resources, particularly gold, which is abundant and has a significant impact on the continent's economy. Gold mining is a notable economic activity in many African countries.
Step-by-step explanation:
The question relates to the abundance of natural resources in Africa. Africa is incredibly rich in various natural resources, including gold, among other minerals. Its wealth in minerals makes it one of the regions with the greatest potential for economic growth.
Specifically, gold is one of the natural resources that is abundant in Africa, aside from others like diamonds, uranium, and copper. Gold and diamond mining are particularly prominent in Southern African countries. While the continent also has reserves of natural gas, coal, and oil, the abundance of these resources varies significantly across different regions. For instance, coal is found in central Mozambique and is abundant relative to other fossil fuels like natural gas, which has more limited reserves.
Therefore, the correct answer would be A. gold, as it is widely available throughout the continent and plays a significant role in the economies of many African countries.
