Which mph range defines Category 4 hurricane?

• A. 74-95 mph some damage
• B. 130-156 mph catastrophic damage
• C. 96-110 mph extensive damage
• D. 111-129 mph devastating damage

Answer: (B)

Wind speed thresholds on the Saffir-Simpson scale are used to estimate the level of damage a hurricane can cause. A Category 4 hurricane is defined by sustained winds from 130 to 156 mph. At this strength, damage is catastrophic: well-built homes can suffer severe structural damage, roofs and walls may fail, trees and power lines are knocked down, and power outages can last weeks to months. The other ranges correspond to weaker categories, with lower winds producing progressively less damage. Since 130-156 mph matches Category 4 and is paired with catastrophic damage, that range is the correct one.
