Which of the following is the focus of the World Trade Organization?

The focus of the World Trade Organization (WTO) is on trade policy. This organization was established to regulate international trade and ensure that trade flows as smoothly, predictively, and freely as possible among nations. The WTO provides a framework for negotiating trade agreements and a dispute resolution process for enforcing participants' adherence to trade agreements. It aims to ensure that trade is conducted fairly and transparently, promoting a level playing field for member countries.

While labor rights, civil rights, and environmental policy are important issues in the global context, they fall outside the core mandates of the WTO. Labor rights may be addressed in other international forums focused specifically on those issues, and environmental policy is often governed by different treaties and organizations dedicated to ecological matters. Hence, trade policy is the singular focus of the WTO, making it the most relevant answer to the question.
