The correct answer is (b) monsoons. Seasonal wind shifts bring heavy rains during the wet monsoon season in regions like Southeast Asia, Australia, Western Africa, eastern South America, and Mexico. These monsoons can lead to flooding, landslides, and mudflows, especially in mountainous areas. Squalls, cyclones, and tropical storms may also occur during these periods, but they are not the primary cause of long-lasting wet seasons.
