Country A has a climate well-suited for agriculture, but few energy resources. Country B is arid but has plentiful access to oil. Which situation will benefit both countries the most?

A.
Country A produces agricultural goods, Country B produces oil, and the countries engage in trade.

B.
Country A produces agricultural goods, Country B produces oil, and the countries do not engage in trade.

C.
Both countries produce agricultural goods and oil, and the countries do not engage in trade.

D.
Both countries produce agricultural goods and oil, and the countries engage in trade.

The situation that will benefit both countries the most is option D. Both countries producing agricultural goods and oil, and engaging in trade.

To understand why option D is the most beneficial, let's break down the advantages and disadvantages of each scenario.

Option A: Country A produces agricultural goods, Country B produces oil, and the countries engage in trade.
- In this scenario, both countries can benefit from their comparative advantages. Country A can focus on agricultural production and export their surplus to Country B in exchange for oil. Country B, with abundant oil resources, can meet the energy needs of both countries.
- By engaging in trade, both countries can specialize in their respective strengths and improve overall economic efficiency. This leads to increased economic growth and prosperity for both nations.

Option B: Country A produces agricultural goods, Country B produces oil, and the countries do not engage in trade.
- Here, both countries are self-sufficient and do not trade with each other. While Country A may have a suitable climate for agriculture, their access to energy resources may be limited. Similarly, Country B may have plentiful oil but might struggle to meet its agricultural needs.
- As a result, both countries would miss out on the benefits of international trade, such as increased production, access to a wider variety of goods, and potential cost savings.

Option C: Both countries produce agricultural goods and oil, and the countries do not engage in trade.
- In this scenario, both countries have the necessary resources to meet their own agricultural and energy needs. However, they do not take advantage of potential efficiencies and benefits that specialization and trade can provide.
- By not trading, both countries may face higher production costs, limited access to certain goods, and miss out on opportunities for economic growth and development.

Option D: Both countries produce agricultural goods and oil, and the countries engage in trade.
- This situation combines the advantages from options A and B. Both countries can specialize in their strengths – Country A focusing on agriculture and Country B on oil production. Through trade, they can exchange their surpluses, creating a mutually beneficial arrangement.
- By engaging in trade, both countries can overcome resource limitations, achieve economies of scale, enhance productivity, and enjoy access to diverse products and services. This can lead to increased economic interdependence and improved living standards for both nations.

In summary, option D, where both countries produce agricultural goods and oil, and engage in trade, will benefit both countries the most by leveraging their respective strengths and maximizing economic efficiency.
