Final answer:
The World Trade Organization (WTO) is the organization aiming to guide nations toward free trade and open markets. It evolved from GATT in 1995 and operates at a global level to remove trade barriers and resolve disputes. Option C is correct.
Step-by-step explanation:
The international organization that has a goal to guide the nations of the world toward free trade and open markets is the World Trade Organization (WTO). Unlike regional trade agreements such as NAFTA or the European Union, the WTO operates at a global level. Its purpose, as stated in various documents and observed throughout its history, is to encourage international trade, reduce trade barriers, and resolve trade disputes among countries.
It emerged from the General Agreement on Tariffs and Trade (GATT) in 1995, with the intention of creating smoother, more predictable, and freer trade flows across the globe. The WTO is also responsible for dealing with the legal aspects of international trade and is often seen as a stepping stone towards a more integrated global economy.
