The correct option is CGPM - Metre Convention, 1875.
Explanation
The International System of Units (SI) is the modern metric system of measurement. Its maintenance and development are governed by international organizations established under a specific diplomatic treaty designed to ensure global uniformity in measurements.
Detailed Analysis:
- CGPM - Metre Convention, 1875 is correct: The Metre Convention (Convention du Mètre) is an international treaty signed in Paris on May 20, 1875. It established the General Conference on Weights and Measures (CGPM), an intergovernmental organization that acts as the supreme authority for the SI unit system. The CGPM meets periodically to ratify changes and improvements to the SI system.
- IUPAC - Vienna Convention, 1985 is incorrect: IUPAC (International Union of Pure and Applied Chemistry) is responsible for chemical nomenclature and terminology. The Vienna Convention (1985) is a multilateral environmental agreement for the protection of the Ozone Layer.
- ISO - Geneva Protocol, 1928 is incorrect: ISO (International Organization for Standardization) develops voluntary international standards for products and services. The Geneva Protocol (1928) is a treaty prohibiting the use of chemical and biological weapons in international armed conflicts.
- BIPM - Kyoto Protocol, 1997 is incorrect: The BIPM (International Bureau of Weights and Measures) is the laboratory and secretariat established by the Metre Convention, but the Kyoto Protocol (1997) is an international treaty committed to reducing greenhouse gas emissions to combat climate change.
Key Takeaway: The Metre Convention of 1875 established the permanent organizational structure (CGPM, CIPM, and BIPM) responsible for maintaining and updating the International System of Units (SI).
