Answer:
C. He should plant vegetation.
Step-by-step explanation:
Planting vegetation can help reduce the impact of shoreline erosion by stabilizing the soil and preventing it from being washed away by water. The roots of the plants help to hold the soil in place, and the leaves and stems can absorb some of the energy from waves and storm surges, reducing their erosive force.
Creating a sand dune or marsh can also help to reduce shoreline erosion, but these options may not be feasible for Conrad's particular situation. Creating a sand dune may require large amounts of sand and ongoing maintenance, and creating a marsh may require significant modifications to the existing shoreline.
Moving the home inland may also not be a desirable solution, as it could be expensive and may not provide adequate protection from high winds and storms.
Therefore, planting vegetation is the most practical and effective solution for Conrad to reduce the impact of his home on the shoreline.
