The correct answer is: High temperatures, low humidity.
Summers in Chhattisgarh are characterized by high temperatures, low humidity, and little rainfall. The average temperature in the summer months is around 35 degrees Celsius, with highs of up to 40 degrees Celsius. The humidity is low, which makes the heat more bearable. There is little rainfall in the summer, which can lead to drought conditions.
The other options are incorrect. Moderate temperatures and high rainfall are characteristic of the monsoon season in Chhattisgarh. Low temperatures and snowfall are characteristic of the winter season. Pleasant weather throughout the year is not characteristic of any season in Chhattisgarh.
