C)body size
D)frictional drag

Question

Quizplus · Accepted Answer

Body size is the single-most important determinant of the efficiency of locomotion among all animals. This is because the metabolic rate of an animal is related to its body mass, and larger animals require more energy to move their bodies. Therefore, smaller animals are generally more efficient in their locomotion than larger animals.
