The correct answer is option 3, rainy season. Tar roads are prone to damage during the rainy season due to several factors. Firstly, heavy rainfall can cause water to seep into the cracks and potholes in the road, leading to further erosion and deterioration. Additionally, the repeated wetting and drying of the road surface weakens the underlying layers of the road, making it more susceptible to damage. The moisture also softens the road surface, making it more prone to deformation and forming potholes. Furthermore, the increased presence of water on the road increases the chances of accidents and skidding. The combination of these factors makes tar roads more vulnerable to damage during the rainy season compared to other seasons.
