Final answer:
The WTO represents a large percentage of the world's population, and although the exact figure isn't provided in the available information, the WTO's membership is significant in global trade. For the current percentage, one should refer to the latest data from authoritative sources.
Step-by-step explanation:
The membership in the World Trade Organization (WTO) represents a significant portion of the world's population. The organization works to streamline, regulate, and support international commerce and plays a pivotal role in global trade policy. Several countries are part of the WTO, reflecting a large percentage of the global population. However, based on the provided information and without a specific current statistic available, one cannot confidently choose between the given options of 'less than three-fourths', 'almost 92 percent', 'almost 95 percent', or 'more than 97 percent'. For the most accurate and up-to-date membership population coverage of the WTO, referencing the latest data directly from the WTO or authoritative sources would be necessary.
