What does the World Trade Organization primarily aim to achieve?

The World Trade Organization (WTO) primarily aims to facilitate international trade rules, making option C the correct choice. The WTO provides a framework for negotiating trade agreements and a dispute resolution process to enforce participants' adherence to these agreements. Its primary mission is to ensure that trade flows as smoothly, predictably, and freely as possible among nations.

By establishing a set of binding rules for international commerce, the WTO helps to reduce barriers to trade such as tariffs and quotas, thereby encouraging countries to engage in trade more readily. The organization promotes fair competition and provides a platform for dialogue, which ultimately fosters global economic cooperation and growth.

The other options do not accurately reflect the core objectives of the WTO. While harmonization of domestic trade laws may be a goal for certain trade agreements, it is not the primary aim of the WTO itself. Promotion of local businesses focuses on domestic economic interests rather than international trade, which goes beyond the scope of the WTO's mission. Regulation of currency exchange rates falls under the jurisdiction of different financial institutions, not the WTO, which is focused on trade policy rather than monetary issues.
