DNA fingerprinting is the method of isolating and making images of sequences of DNA. The technique was developed in 1984 by Alec Jeffrey. If a small amount of DNA is available for fingerprinting, a polymerase chain reaction may be used to create thousands of copies of a DNA segment. A DNA profile is a small set of DNA variations that is very likely to be different in all unrelated individuals, thereby being as unique to individuals as are fingerprints. It is having varied applications in DNA tests for identity and relationships, paternity, forensic studies, polymorphsim, etc.

Thus, the correct answer is option B.
