Which of the following best describes 'intergenerational equity'?

The correct option is Fair use of resources to ensure availability for future generations.

Understanding Intergenerational Equity:

Intergenerational equity is a concept of fairness or justice between generations. It emphasizes that the current generation holds the Earth and its natural resources in trust for future generations, and therefore has an obligation to manage and consume resources responsibly without depleting or compromising them for the people of tomorrow.

Key Concept:

While intragenerational equity focuses on fairness and distribution of resources among people living in the present day (across different income groups or nations), intergenerational equity specifically focuses on the long-term sustainability and stewardship of environmental, economic, and cultural assets across time—from the present generation to future generations.
