elasticity means the ability of a material to retain its orginal form immediately after releasing a force from it. in the case of iron it retains its orginal state after releasing force. but in the case of rubber it take some time to retain its orginal form because rubber is a viscoelastic material. in the case of rubber some energy is stored in the material and after time passes the energy leval comes down and it gets its orginal shape. there is one important point behind this, in the case of iron the molecules are arranged in a ordered manner therefore it is more crystalline, but in the case of rubber there is crystalline as well as amorphous part, therfore some part of energy is stored in it.

it is so bcoz while comparing the elasticity of two substances the life of this property is also taken into account & if a rubber is stretched & kept in the same postion for long period it remains that shape even after released while this does not take place in the case of iron.

For a given rigidity? in all possibility iron. in case you're taking a rod of iron and a rod of rubber of the comparable length and shape, protruding into area with one end held inflexible, and draw close the comparable weight on the tip of the two, i could anticipate that the iron could slightly be deflected with the help of a weight that would wreck the rubber. And once you do away with that weight from the iron rod, it's going to bypass particularly plenty lower back to its unique shape. For a given tension? in all possibility rubber. Rubber can particularly be stretched to many cases it unique length and return to very almost precisely its unique shape once you enable it bypass. Iron can no longer. So it relies upon on what you recommend.

Unfortunately in Physics elastic is opposite of elastic in normal common sense. Based on that iron is more elastic.(see bellow)

Iron is not more elastic than rubber.

Which Is More Elastic

elasticity ,more commonly mistaken as the property of a body to be stretched
elasticity means the capacity of the body to resist the change in shape & regain its original shape after the deforming forces cease to act

Who considers? If someone considers, as your presumption, it is wrong. Are you talking about Tensile Strength or Elasticity.

Because iron can readily regains its actual structure on removal of applied force on it.
