The correct answer is A. A material is said to be perfectly elastic if it regains its original shape on removal of the load.
Option B is incorrect because a material that regains its original shape partially on removal of the load is said to be partially elastic.
Option C is incorrect because a material that does not regain its original shape at all is said to be plastic.
Option D is incorrect because it is not one of the possible answers.
