Quizplus · Accepted Answer

A breakwater is constructed offshore to reduce the energy of waves and protect the beach from erosion. Similarly, an island offshore breaks the waves and traps sand behind it to form a tombolo, which is a natural coastal structure with the same protective function as a breakwater. The other options (A,C,D) do not produce the same effect as a breakwater.
