Right Answer is:

Groynes

SOLUTION

A groyne is an active structure extending from the shore into the sea, most often perpendicular or slightly oblique to the shoreline.

Groynes:- These are structures ‘normal’ to the shore, meaning that they run perpendicular to the line of the shore and hence intrude into the sea from the shore. Their effect is to interrupt the usual natural movements of sediments along the shore, thus retaining beach materials that would otherwise be lost from the particular stretch of shore being protected. They can be constructed in a variety of forms and materials, including timber, masonry and concrete.
