The correct answer is D) Drag the raft ashore and lash it down for a shelter. The primary goal when reaching shore in a liferaft is to get the raft and its occupants safely onto land and establish a secure shelter. Dragging the raft ashore and lashing it down provides a stable, protected base from which to access the raft's provisions and begin preparing for rescue or survival on land. The other options are not recommended, as setting the raft back out to sea (A) would risk being lost at sea again, starting a fire (B) may be difficult without proper equipment, and retrieving provisions (C) should be done after securing the raft on shore.
