Answer:
The answer is C: state that bodies wit increased mass or volume to surface are optimal for cold climates.
Step-by-step explanation:
The bergmann rule establishes that the species of animals that maintain their body temperature within normal limits regardless of the ambient temperature, when they live in cold weather, tend to be of greater volume and weight than those of the same species that live in other warmer regions. A clear example of this are the North Pole penguins, which are larger than African penguins.
