Right option is (c) Allen’s rule
 
To elaborate: Allen’s rule is an eco-geographical rule which states that in a cold climate, mammals possess shorter ears and limbs to minimize heat loss.  It was stated by Joel Asaph Allen in 1877. It is a form of an adaptation done for survival in colder regions.
