For Perfectly Elastic - 1.
For Elastic - 0 to 1.
For Inelastic - 0.
For Elastic - 0 to 1.
For Inelastic - 0.

There is no perfect elastic body.
An object that gains it's original shape after removal of the load is known as an elastic body.
So according to my point of view answer is 1.

Question is asked for elastic bodies hence, it's an elastic collision that is no K. E is lost.
Therefore, the Coeff is 1.
Therefore, the Coeff is 1.

The coefficient of restitution = Relative speed after collision/Relative speed before the collision.
The coefficient of restitution for perfectly elastic bodies is 1 and for perfectly inelastic is 0. And it varies for 0 to 1. So, the correct answer would be [A].

Friends, how to find out the co-efficient of restitution. By using velocity and height of the object after impact.
