\nThe correct option is C) Rapid withdrawal of water away from the beach.
\n<\/section>\n
\nThe most common natural warning sign of an approaching tsunami, particularly for the first wave, is a sudden and significant recession of the sea from the coastline, exposing the seabed. This happens because the trough (low point) of the tsunami wave often reaches the shore before the crest (high point). This is an immediate signal that a large wave is approaching and coastal areas should be evacuated.
\n<\/section>\n
\nA thundering noise can sometimes be heard as the tsunami wave breaks, but the water receding is often the first visible sign. Squally winds and rainfall are associated with meteorological phenomena like cyclones, not tsunamis which are primarily caused by underwater geological events. Rapid landward movement of water *is* the tsunami arriving, not a warning beforehand.
