The correct answer is (d) 164.

The World Trade Organization (WTO) is an international organization that deals with the rules of trade between nations. As of February 2023, it has 164 member countries.

The WTO was founded in 1995, replacing the General Agreement on Tariffs and Trade (GATT). The GATT was established in 1947 and was the first multilateral agreement on trade.

The WTO’s main purpose is to help countries trade more freely. It does this by negotiating trade agreements, settling trade disputes, and providing technical assistance to developing countries.

The WTO is headquartered in Geneva, Switzerland.
