Solution

The correct option is C Bear
In a bear, the surface area is less as compared to volume. Thus, it Will generate more heat and radiate less making it suitable for living in cold climate.

Q. Birds and mammals being homeothermic (capable of maintaining constant body temperature) have evolved a mechanism to regulate their metabolic rate. An inverse relationship is observed between metabolic rate and body weight from the plot of the rate of oxygen consumption versus body weight of different mammals. On the other hand, there is the directly proportional relationship between metabolic rate and surface area to volume ratio. From the given figure it is evident that more internal heat per gram of body weight is generated by shrew and more heat is lost to the environment than the horse. Thus maintenance of constant body temperature is more difficult for small animals in cold weather.
