Which organization is referred to as the National Standards Body (NSB)?

The National Standards Body (NSB) is specifically recognized as the entity that represents a country's interests in the development and implementation of international standards, particularly in relation to the International Organization for Standardization (ISO). As such, the primary role of an NSB is to facilitate the participation of a country in the international standards-making processes, ensuring that national viewpoints are considered in the formulation of global standards.

This encompasses advocating for national industry needs, promoting the use of standards within the country, and organizing the country’s engagement with ISO activities. Thus, option B accurately describes the purpose and function of the NSB.

In contrast to this, the other choices pertain to different organizations or functions that do not align directly with the definition and role of an NSB. For example, while the development of international standards is a related concept, it does not capture the unique function of representing a country at ISO. Similarly, organizations focused on specific industries, like oil and gas, and bodies that monitor compliance with laws address narrower scopes of regulation and operational standards rather than the broader representation and advocacy of national interests in the international standardization context.
