As Predicted by Bergmann's and Allen's Rules, Having a Lean

As predicted by Bergmann's and Allen's rules, having a lean, long-limbed body type in an equatorial climate provides an individual with

A) greater surface area in relation to body mass which facilitates body heat dissipation.
B) less surface area in relation to body mass which facilitates body heat dissipation.
C) a constant surface area in relation to body mass, facilitating climatic adaptation.
D) less surface area in relation to body mass, facilitating body heat retention.
E) greater surface area in relation to body mass, facilitating body heat retention.
