What was the predecessor of WTO?

Answer (A), The World Trade Organization (WTO) was established on January 1, 1995, and its predecessor was the General Agreement on Tariffs and Trade (GATT), which was established after World War II. The GATT had been the rules for the trading system since 1948, and the WTO is considered the successor to the GATT. The WTO is relatively young, but the multilateral trading system that the GATT established is over 75 years old.
