Explanation:

A heatwave is a period of abnormally high temperatures, more than the normal maximum temperature that occurs during the summer season in the North-Western and South Central parts of India.

The India Meteorological Department (IMD) classifies heat waves according to regions and their temperature ranges.
Recently, a study has found a spatial shift of heatwaves in India, now occurring in new regions in the country.
It also added that the eastern and western coasts, which are currently unaffected by heatwaves, will be severely impacted in the future.
Also, heatwaves were found in southern Madhya Pradesh, Andhra Pradesh, Karnataka and Tamil Nadu, where they would traditionally not take place.
The heatwave is considered when the maximum temperature of a station reaches at least 40°C for Plains and at least 30°C for Hilly regions.
An increase of 5°C to 6°C from the normal temperature is considered to be heat wave condition.

Hence option 4th is correct.
