The premonsoon mango showers occur predominantly in

Answer: Option D

The premonsoon mango showers occur predominantly in Kerala and Karnataka. These showers are a meteorological phenomenon that marks the onset of the southwest monsoon season in India. The southwest monsoon winds bring moisture-laden air from the Arabian Sea to the Indian subcontinent. As this moist air encounters the Western Ghats, it is forced to rise, cool, and condense, leading to the formation of premonsoon showers.

Kerala and Karnataka are the states located along the western coast of India, adjacent to the Western Ghats. The geography of this region, with the presence of the Western Ghats, makes it conducive for the occurrence of these early rain showers before the onset of the full-fledged monsoon. These showers are vital for agricultural activities, especially for the cultivation of crops like mangoes.
