The correct option is D. Zambia. Explanation of the Correct Answer Zambia is known for its significant export trade that is heavily dominated by copper, a mineral that plays a crucial role in its economy. Here’s a detailed breakdown of why Zambia is the correct answer:

1. Economic Dependence on Copper:
2. Zambia is one of the largest producers of copper in Africa. The mining sector, particularly copper mining, accounts for a substantial portion of the country's GDP and export earnings. In fact, copper exports can make up over 70% of Zambia's total export revenue.
3. The country has rich copper deposits, primarily located in the Copperbelt region, which has been the backbone of its economy for decades.
4. Historical Context:
5. The mining industry in Zambia has a long history, dating back to the colonial era when copper mining was established as a key economic activity. This historical reliance has continued into the present day, making copper a defining feature of Zambia's trade profile.
6. Global Market Influence:
7. Zambia's economy is sensitive to global copper prices. Fluctuations in the international market for copper can significantly impact the country's economic health, employment rates, and government revenue.

Why the Other Options Are Incorrect A. Central Africa Empire: - The Central African Empire (which existed from 1976 to 1993) is not a current country and does not have a defined export profile today. Even during its existence, it was not known for a single dominant mineral export like Zambia is with copper. B. Uganda: - Uganda's economy is more diversified compared to Zambia's. While Uganda does export minerals such as gold and tin, its export trade is not dominated by a single mineral. Agriculture, particularly coffee, also plays a significant role in Uganda's economy. C. Kenya: - Kenya's economy is primarily based on agriculture, tourism, and services. While it does have mineral resources, such as soda ash and fluorspar, these do not dominate its export trade. Kenya's exports are more varied and do not rely heavily on a single mineral. Summary of Key Points

• Zambia's Dominance in Copper: Zambia's economy is heavily reliant on copper, making it the country with an export trade dominated by a single mineral.
• Economic Impact: Copper mining significantly contributes to Zambia's GDP and export revenues, highlighting its importance.
• Comparison with Other Countries: Other options (Central Africa Empire, Uganda, and Kenya) do not have a single mineral that dominates their export trade like Zambia does with copper.

Revision Summary

• Zambia's export trade is primarily dominated by copper, accounting for a large percentage of its GDP and export earnings.
• The Copperbelt region is crucial for copper mining in Zambia.
• Other countries listed (Central Africa Empire, Uganda, Kenya) do not have a single mineral that dominates their exports.
• Understanding the economic impact of mineral exports is essential for grasping the trade dynamics of countries like Zambia.
