Step 1: Definition of sustainable development.
The World Commission on Environment and Development (Brundtland Commission, 1987) defined sustainable development as:
“Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
Step 2: Eliminate incorrect options.
- (A) Refers only to the present, but ignores future sustainability.
- (B) Refers only to the future, but neglects current needs.
- (D) Refers to the past, irrelevant to sustainability.
Only (C) fits the official definition.
