Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
Most copper compounds tend to settle down near the water sediments or near the soil particles and can be monitored from there.

Copper can be discharged into the earth by both natural sources and human exercises. Copper is regularly found close to mines, modern settings, landfills and waste removals. Most copper mixes will settle and will undoubtedly either water silt or soil particles.
Copper doesn't separate in the earth and due to that it can gather in plants and creatures when it is found in soils. At the point when the dirt of farmland are dirtied with copper, animals will assimilate fixations that are harming to their well being.
