the correct answer is three

Only beach nourishment uses a hard structure to manage erosion.

Both relocate materials back to the shore

Beach nourishment refers to the addition of sand on the beach to reduce the erosion effect by water currents.

Vegetation management is the (re)plantation of plants to reduce the erosion effect on beaches caused by waves.

In the statements given above, the addition of hard structure doesn't primarily means beach nourishment, likewise, vegetation management doesn't replace the sand on the beach but rather prevents sand erosion. However, vegetation management brings in plants that hold the sand, especially on dunes. Floods cannot be controlled by beach nourishment but with the help of plants, their impact can be minimized.

Therefore, the correct answer is option

3. Only beach nourishment uses a hard structure to manage erosion.
