Very small animals are rarely found in polar regions. Pick out the main reason in support of this.

A
They have a larger surface area relative to their volume
B
They tend to lose body heat slowly, when it is cold outside
C
They have a smaller surface area relative to their volume
D
They can generate more body heat through metabolism by expending much energy

Solution:

Small animals have a larger surface area relative to their volume, so they tend to lose body heat very fast when it is cold outside; then they have to expend much energy to generate body heat through metabolism. This is the main reason why very small animals are rarely found in polar regions.
