Metabolic Rate Increases with Animal Mass Raised to the Three-Quarter

Metabolic rate increases with animal mass raised to the three-quarter power, a relationship known as the three-quarter power law. If instead metabolic rate scaled proportionally to mass, then an animal twice the mass of another animal would have a metabolic rate:

A) more than twice that of the other animal.
B) less than twice that of the other animal.
C) twice that of the other animal.
D) equal to the other animal.
E) four times that of the other animal.
