Quizplus · Accepted Answer

The groin is a type of hard stabilization structure that is built perpendicular to a beach in order to trap sand and prevent erosion. It is typically constructed using large boulders or concrete blocks. In the figure, structure B fits this description and is therefore the groin. Structures A and C are examples of other types of hard stabilization structures, such as seawalls and revetments.
