Correct option is B
Elasticity is defined as the ability of a material to return to its original shape after deformation. The measure of elasticity is given by Young’s modulus (E)—a higher value of EEE means greater elasticity.
Let's compare the Young’s modulus of the given materials:
· Rubber → 0.01 to 0.1 GPa
· Steel → 200 GPa (Highest)
· Aluminium → 70 GPa
· Wrought iron → 190 GPa
Since Steel has the highest Young’s modulus (~200 GPa), it is the most elastic material in the scientific sense.
