What is the average temperature range for mastic?

The average temperature range for mastic is indeed accurately reflected by the choice indicating a range of -20°F to 200°F. This range demonstrates mastic's capability to maintain its properties and performance over a wide spectrum of temperatures, making it suitable for various applications where temperature fluctuations can occur.

Mastic is a type of adhesive commonly used in construction and automotive industries due to its flexibility and resilience. Being effective at both lower temperatures and up to 200°F ensures that it can function properly in diverse environments, whether it's exposed to cold weather conditions or higher temperatures.

The temperature ranges given in the other options do not fully encompass the wide operational capabilities of mastic, thereby making them less suitable choices. The proper range not only highlights its versatility but also aligns well with the requirements typically sought in insulation materials.
