The difference between the temperatures of the hottest and coldest months of a place is known as the "annual range of temperature". This refers to the difference between the highest and lowest temperatures experienced over the course of a year in a specific location. For example, a place that experiences very hot temperatures in the summer and very cold temperatures in the winter will have a larger annual range of temperature than a place where temperatures are more consistent throughout the year. Therefore, the correct option is "annual range of temperature".
