During aerobic cellular respiration, oxygen consumed by homeothermic animals at 5oC is greater than the oxygen consumed at a higher temperature. This is most likely explained by which of the following statements?

A. The respiration rate is higher at 35oC; therefore the oxygen consumption is lower because less oxygen is necessary with the higher respiration rate.
B. The animals at 5oC were more active than the animals at 35oC; therefore more oxygen was consumed.
C. The animals at 5oC had lower metabolic rate than the animals at 35o
D. The respiration rate is higher at 5oC because the animal would need more energy to maintain their normal body temperature.
