The International Organization for Standardization (ISO) is the recognized body responsible for developing and publishing international standards across a wide array of industries and sectors. This organization plays a vital role in facilitating global trade by establishing standards that ensure quality, safety, and efficiency in products and services.

By creating these standards, ISO helps businesses across different nations to align their processes and improve interoperability. This is particularly important in logistics, transportation, and distribution, where consistency in standards can affect everything from product quality to environmental sustainability.

The other organizations listed do not have the authority to set ISO standards. For example, the World Trade Organization primarily focuses on regulating international trade agreements and policies but does not develop standards. The International Standards Institute is a lesser-known and sometimes informal term that does not correspond to an organization with the same scope or recognition as ISO. Similarly, the Global Standardization Authority isn’t an established entity recognized for setting these standards. Thus, the International Organization for Standardization is indeed the correct answer as it is the principal organization tasked with this critical function.
