The correct option is B can maintain homeostasis
Temperature is the most relevant environmental factor, and the average temperature is never constant, it varies seasonally. The physiological functions and the geographical distribution of many plants and animals are governed by temperature.
Homeostasis refers to the capacity of a living organism to maintain the stability of diverse internal variables such as temperature, acidity, water level etc.
The purpose of homeostasis is to maintain the established internal environment without being overcome by external stimuli that exist to disrupt the balance.
Some animals are able to maintain homeostasis by physiological means to ensure constant temperature and osmotic concentration etc. are considered as regulators.
