Explanation
The correct answer is (c) World Commission on Environment and Development, 1987.
The term "sustainable development" was popularized by the report titled "Our Common Future," also known as the Brundtland Report, published by the World Commission on Environment and Development (WCED) in 1987. The WCED was established by the United Nations in 1983 and was chaired by Gro Harlem Brundtland, the former Prime Minister of Norway.
The report defined sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." It emphasized the interconnectedness of environmental, social, and economic aspects of development and called for integrating these dimensions to achieve sustainable outcomes.
The term gained further prominence and recognition at the United Nations Conference on Environment and Development (UNCED), held in Rio de Janeiro in 1992. The Rio Declaration and Agenda 21, both outcomes of UNCED, further reinforced and promoted the concept of sustainable development.
However, it was the World Commission on Environment and Development in 1987 that brought the term "sustainable development" into common use through the publication of the Brundtland Report.
Therefore, the correct answer is (c) World Commission on Environment and Development, 1987.
