Solution

The correct option is C Both 1 and 2
The Young's Modulus of a material represents its elasticity. Higher the value of Young's modulus, more stress can the material sustain without permanent deformation. Steel has higher value of Young's Modulus tan that of copper, so its more elastic than copper.

Both statements are correct.
