A
True
💡 Explanation:
Modulus of elasticity = $\dfrac { stress }{ strain } $ and, stress = $\dfrac { Force }{ Area } $
$\therefore $ Elasticity $\alpha \dfrac { 1 }{ Area } $
As follow shaft, so, elasticity of the follow shaft is more than a solid one. As elasticity measures rigidity. So, hollow shaft is stronger.
