Coefficient of Restitution.
Plastic Collision = 0.
Elastic Collision = Between 0-1.
Perfectly Elastic Collision = 1.
Plastic Collision = 0.
Elastic Collision = Between 0-1.
Perfectly Elastic Collision = 1.

There is difference in word perfectly elastic and elastic, e=1 perfectly elastic collision not for elastic collision.

COR is 1 for completely elastic collision, and elastic collision means collision between elastic bodies only.
COR ranges from 0-1 for elastic bodies/collision.
COR is 0 for plastic bodies/collision.
Here he has mentioned elastic bodies only. Had he mentioned completely elastic, then it would be COR=1. So here COR is not equal to 1. Hence the option is also correct.

COR is the ratio of relative velocity after impact to the relative velocity before impact.

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.

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.

Guys how can an elastic collision occur unless and until the bodies are elastic.?

For perfectly elastic cor : 1.
For perfectly inelastic cor : 0.
For partially elastic cor: 0 <e<1.
For perfectly inelastic cor : 0.
For partially elastic cor: 0 <e<1.
