The coefficient is 1 for an elastic collision, less than 1 for an inelastic collision, zero for a completely inelastic collision, and greater than 1 for a superelastic collision.

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.

Can anyone explain clearly regarding the difference of elastic bodies and elastic collision. I think then it will be clear to differentiate between the coefficients.

Coefficient of restitution for:
Perfectly plastic bodies 0.
Plastic body is b/w 0-1.
Elastic bodies b/w 0-1.
Perfectly elastic bodies 1.
Perfectly plastic bodies 0.
Plastic body is b/w 0-1.
Elastic bodies b/w 0-1.
Perfectly elastic bodies 1.

A body which can regain its original shape and size after removing the load (if load cause deformation in body) is called elastic body.

Coefficient of restitution for elastic bodies is 0 - 1.
Coefficient of restitution for perfect elastic bodies is 1.
So answer is B.
Coefficient of restitution for perfect elastic bodies is 1.
So answer is B.

An elastic collision is defined as one in which both conservation of momentum and conservation of kinetic energy are observed.

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 difference between elastic & perfectly elastic body is if the body is perfectly elastic then the value of e is 1.
