Understand that the question is about the organization responsible for defining and governing the metric or SI system of measurement.
Recall that the International System of Units (SI) is maintained by an international organization to ensure global standardization.
Identify the International Bureau of Weights and Measures (BIPM) as the organization established by the Meter Convention to maintain and define the SI units.
Recognize that other organizations like NIST, IUPAC, and WHO have different roles: NIST focuses on standards in the U.S., IUPAC on chemical nomenclature, and WHO on health-related standards.
Conclude that the correct governing body for the metric or SI system is the International Bureau of Weights and Measures (BIPM).
