Final answer:
The World Bank focuses specifically on poverty alleviation in low-income countries by offering financial and technical assistance for development programs aimed at improving economic prospects and quality of life.
Step-by-step explanation:
The international organization that is specifically concerned with poverty alleviation in low-income countries is The World Bank.
The World Bank was established along with the International Monetary Fund (IMF) after the Bretton Woods Conference and became operational in 1946.
While both institutions were created to help rebuild and stabilize the post-war global economy, The World Bank focuses on providing financial and technical assistance to developing countries for development programs (e.g., infrastructure, healthcare, education) that are meant to improve economic prospects and quality of life.
On the other hand, the IMF focuses more on macroeconomic issues and providing countries with short-term financial assistance to stabilize their economies.
It is important to note that although the World Trade Organization (WTO) and the General Agreement on Tariffs and Trade (GATT) play significant roles in international economics, they are generally focused on creating a regulatory environment conducive to trade rather than direct poverty alleviation.
Therefore, the correct answer to the question is D. The World Bank.
