a) False: The young's modulus of steel is higher.Elasticity is the capability of an object to return to its former shape once a load inducing strain is removed. If you were to drop a steel ball on a very hard surface, it would probably bounce higher than than rubber. If you drop it on a softer surface, because it would deform less, then the surface it is to bounce off will be the one deforming, so the bounce would be a function of the elasticity of the floor, not of the ball.
b) False : The stretching of the coil is determined by its young modulus which is longitudinal stretching.
