The correct answer is D: to keep them from flooding when water levels rise. Some beach houses along the North Carolina coast are raised on stilts to protect them from potential flooding caused by storm surges or rising water levels during hurricanes, heavy rainfall, or other natural disasters. The stilts elevate the house above ground level, preventing water from entering the lower levels of the structure. This helps safeguard the house and its contents from water damage. Additionally, raising the house on stilts can help improve the overall stability of the structure and minimize the impact of strong winds.
