Assertion (A): A hippopotamus has thicker legs for its size than a mouse does. Reason (R): The compressive load on the leg bones of an animal depends on its weight, which in turn varies as the cube L³ of a representative linear dimension L such as its length or height. The strength of a bone, however, depends on its cross –sectional area which for similar animals varies as L². A large animal must have relatively thicker leg bones than a small one because L³ increases faster than L²

A. Both A and R are true, and R is the correct explanation of A

B. Both A and R are true, but R is not the correct explanation of A

C. A is true but R is false
