Option 1: Kalbaisakhi
This option is incorrect because Kalbaisakhi refers to the pre-monsoon thunderstorms that occur in the Indian subcontinent during the month of Baisakhi (April-May), mainly in the states of West Bengal, Bihar, and Assam.
Option 2: Mango Showers
This is the correct answer. Mango showers are the rains that occur during the hot weather season (mid-March to mid-June) in Karnataka. These showers are named after the mango fruit, as they are considered beneficial for the growth and cultivation of mango trees.
Option 3: Loo
Loo is not the correct answer for rains caused by thunderstorms. Loo is a term used in Northern India to describe hot and dry winds that blow during the summer months, particularly in the states of Uttar Pradesh, Rajasthan, and Haryana.
Option 4: Cherry blossoms
Cherry blossoms are not related to rains caused by thunderstorms in Karnataka. Cherry blossom refers to the beautiful flowering of cherry trees, mainly observed in countries like Japan and the United States during spring.
In conclusion, the correct answer for rains caused by thunderstorms during the hot weather season in Karnataka is Mango Showers.
