Solution

The correct option is B All the above
DNA fingerprinting is a method used in the identification of the genetic information (DNA) in a person's cell. It is a forensic technique used to identify an individual by the characteristics of the DNA. It is also useful to identify the identity and relation of an individual with others. This method is also used in the study of polymorphism where the variation in DNA arising through mutation at non​-coding sequences can be detected.
Thus the correct answer is option D.
