Concept:Conservation is the planned, sustainable management of natural resources to prevent their exploitation, destruction, or depletion.
Explanation:Natural resources such as mineral resources, soil, water, forest, and wildlife occur in nature and are essential for human survival.
These resources can be conserved through controlled use, recycling, replanting, and legal protection.
Domestic wastes, however, are discarded materials produced by households and are not natural resources.
Conservation does not apply to waste materials because they have no intrinsic value to preserve for future use.
Instead, domestic wastes are handled through proper disposal, recycling, or reduction at the source.
Therefore, they are the resources that cannot be conserved in the same sense as natural assets.
Answer:The correct option is
D. domestic wastes.
