The correct answer is: May.
Haryana is a state in northern India. It is located in the Indo-Gangetic Plain, and has a hot, humid climate. The average temperature in Haryana ranges from 15 degrees Celsius (59 degrees Fahrenheit) in January to 40 degrees Celsius (104 degrees Fahrenheit) in May.
The hottest month in Haryana is May. The average temperature in May is 35 degrees Celsius (95 degrees Fahrenheit). The maximum temperature in May can reach up to 45 degrees Celsius (113 degrees Fahrenheit).
The reason why May is the hottest month in Haryana is because it is the month when the sun is directly overhead. The sun’s rays are more direct in May than in any other month of the year. This means that the sun’s energy is more concentrated, and the temperature is higher.
The other options are incorrect because they are not the hottest months in Haryana. February is the coldest month in Haryana, with an average temperature of 15 degrees Celsius (59 degrees Fahrenheit). March is a warm month, with an average temperature of 25 degrees Celsius (77 degrees Fahrenheit). April is a hot month, with an average temperature of 30 degrees Celsius (86 degrees Fahrenheit).
