Which of the storm damages listed below is responsible for about 90% of all deaths in tropical cyclones?

I believe the answer is a storm surge. 
Storm surge are produced by the force of a hurricane's winds pushing water toward the shore. A storm's winds can cause an abnormally large rise in the water level, which can destroy buildings, bridges and roads; sweep people away; and cause damaging erosion to beaches and dunes. They occur when a dome of water sweeps across the coast near the point where the eye makes landfall.
