• C. Statement 1 is correct and statement 2 is incorrect
• D. Both statements 1 and 2 are incorrect

Answer 1

The correct option is : B

Both statements 1 and 2 are incorrect.

Small animals have a larger surface area to volume ratio, this means a higher surface area to lose body heat, therefore these animals lose body heat very fast when it is cold outside and must expend metabolic energy to maintain body heat.
