Strain energy is equal to the work done by system and it may be regained by allowing the body to relax.
The best example of this is a clockwork device which stores strain energy and then gives it up.
After elastic limit we can't regain the original one, so up to elastic limit only is the right answer.

Actually it is the property the energy stored in the body. Perfectly upto elastic limit resilience. Upto fracture toughness. Max energy upto elastic limit proof resilience. It is not specifically upto elastic limit I think answer is wrong. Please give me suggestion.

If force applied on a body within elastic limit, body change its shape, strain also produced in a body at that time. When remove the force applied on a body, then body gets its original shape. Here required energy to get original shape is called strain energy.

Best answer among this option is A. But in actual strain energy is the energy stored till proportional limit because only under proportional limit we can use stress-strain relationship (in the region after proportional limit it flow stress relationship).

Strain energy is the energy which is stored in the body which we can get back after removal of external force. It is only possible only up to elastic limit. Above which rest of the stored energy released in the form of heat.

Strain Energy is Potential energy stored in the body and it will always be stored in that form unless that leads to bond breaking and plastic deformation. So, Yes, the strain energy is up to elastic limits.

Strain energy is energy absorbed by member when work done by load deforms that member. It may be elastic or more than that. So energy absorbed by a member within elastic region is called resilience.

Strain energy is area under stress-strain curve. So how can it be within elastic limit? After yield point you will find area under stress-strain curve that means specimen has strain energy.

When the load is acting on the body, it tends to elongate or it changes its length (either decreasing or increasing) that is called strain the energy applied is known as strain.

Take a example of a spring so when you elongate it within elastic limit (i.e point till which it can regain its original shape and size) by doing so strain energy is stored.
