Warden: The fences we set at the foot of the dune trap sand blowing off the beach, and the dune has risen a metre in five years. Sand a dune gains it takes from the beach in front of it, so that beach should have dropped. It has not dropped at all, and along the same stretch it is a little wider than it was.

Which one of the following, if true, most helps to explain the discrepancy described above?

AStorms in winter cut into the dune and carry part of the metre it has risen back to the beach.

BA dune that has risen a metre shelters the beach below it, and less of that beach's sand is carried inland now than in the five years before any fences went in.

CWaves have been carrying sand ashore from a bar lying some way out, and in five years they have put more on the beach than the fences have held.

DAlmost the whole metre the dune has risen in five years came in two winters when onshore gales ran for weeks at a time.

ESand lifted over the crest has built a low ridge on the dune's landward side that was not there when the fences went in.
