What environmental temperature range is typically required for transporting animals by air?

When transporting animals by air, ensuring their comfort and safety is paramount, which includes considering the environmental temperature. The correct answer indicates a range that accommodates the thermal needs of various animals during transit.

The range of 45°F to 85°F provides flexibility to account for different species and their specific temperature tolerances. Many animals can experience stress or health issues if exposed to extreme temperatures, and this range helps mitigate such risks. It is broad enough to ensure various animals can adapt during transport, considering variations in breed, species, and their inherent differences in climate acclimatization.

The other options present narrower or less suitable temperature ranges that might not sufficiently support the health and wellbeing of all animals during air transport. Such restricted ranges could lead to situations where certain animals might be exposed to temperatures that are uncomfortable or harmful, affecting their health and the success of the transportation process.
