The correct answer is: A. Sub-humid climate
A sub-humid climate is a climate that is characterized by a moderate amount of precipitation. The average annual precipitation in a sub-humid climate is between 25 and 50 inches. The Köppen climate classification system defines a sub-humid climate as a climate with a dry season that lasts for less than four months.
The Northern region of Haryana has a sub-humid climate. The average annual precipitation in the Northern region of Haryana is 30 inches. The dry season in the Northern region of Haryana lasts for about two months.
The other options are incorrect because they do not describe the climate of the Northern region of Haryana accurately.
Option B, dry climate, is incorrect because a dry climate is a climate that receives less than 25 inches of precipitation per year. The Northern region of Haryana receives more than 25 inches of precipitation per year.
Option C, humid-evergreen climate, is incorrect because a humid-evergreen climate is a climate that receives more than 100 inches of precipitation per year. The Northern region of Haryana receives less than 100 inches of precipitation per year.
Option D, temperate-humid climate, is incorrect because a temperate-humid climate is a climate that has a warm summer and a cool winter. The Northern region of Haryana has a hot summer and a warm winter.
