Answer 2

Explanation:  

• An elephant's weight is so much that, The cross-sectional areas of the bones are increased by nature due to stress =  force/area  to bring the stress on the bones under the permissible limit. So, an elephant's bones are thicker than proportionate.

Or  

• The elephant weighs more than a mouse, But it's the same material that makes their bones. This means that, to maintain the weight of an elephant , One's bones must undergo less stress. A greater cross-sectional area is decreased bone tension. Hence the bones of an elephant are thicker.
