Correct option (D) Allen's Rule does not apply to the length of animals' extremities in warmer areas.

According to Allen's Rule, various animal extremities such as arms, legs, ears, or nose are shorter in the cooler regions of a species' range than in the warmer parts. This is due to the fact that mammals from colder areas develop shorter ears and limbs to reduce heat loss.

It is also mentioned that aquatic mammals, such as seals, have a thick layer of fat beneath their skin that acts as an insulator and decreases heat loss. This suggests that Allen's Rule applies to the length of extremities in both colder and warmer areas.

Option d is the correct answer.
