• A. Storm surge
• B. High winds
• C. Rains
• D. Lightning

Answer: (A)

Storm surge is the most potentially destructive force of a major hurricane. It’s the abnormal rise of seawater driven by the hurricane’s winds and central pressure that pushes a wall of water onto the coast. This surge can flood large coastal areas, overwhelm seawalls and levees, collapse structures built to resist wind, and drown people who are unable to evacuate in time. The reason it stands out is that the water can reach far inland, arrive with little warning, and cause rapid, catastrophic damage to buildings, roads, and utilities, leading to widespread and long-lasting destruction. While high winds can topple structures and heavy rains can cause inland floods, the surge acts as the primary flood mechanism on the coastline and is the leading factor in storm-related fatalities. Lightning is not a major contributor to destruction in these events.
