Since, in elastic collision momentum and K. E both remain constant. So, I agree.

For perfectly elastic bodies, losses of KE during collision is zero.
For elastic body impact coefficient of restitution is 0 to 1. So, there is some loss in KE.
For elastic body impact coefficient of restitution is 0 to 1. So, there is some loss in KE.

I too think it is option B.

Loss of kinetic energy in perfectly elastic collision is should be zero but for elastic collision it may be vary between 1 to 99% loss.

Yes, right I agree with you @Ujjawal Aggarwal.

Energy can neither be created nor be destroy, it can only be transfer from one to another body. So, either the body is perfectly elastic or only elastic it doesn't matter. So, I agree.

It says elastic body, not perfectly elastic so answer Will be B- Disagree.

Energy loss is zero by the way of energy conservation law.
