The structure shown in the diagram is a groynes. Groynes are built perpendicular to the shoreline in order to trap sediment and prevent erosion. Sediment will be deposited on the side of the groyne that is opposite to the dominant direction of longshore drift. In this particular diagram, the longshore drift appears to be coming from the left side, so sediment will be deposited on the right side of Groyne A. Therefore, the correct answer is C, Groyne A.
