Then how do we define elasticity and how do we measure it ?
Elasticity is a measure of how well a material returns to its original shape and size i.e. it is the ratio of stress over strain. It does not mean how 'flexible' a substance is or how much it can be stretched.
And the Young's Modulus measures the resistance of a material to elastic (recoverable) deformation under load. So keeping in view the definition of elasticity, we can say that Diamond is more elastic than both of them, i.e. it has more ability to resist the elastic deformation and return to its original shape.

Yes, you got it right
Diamond
is more elastic than both of them
