Solution

The correct option is B Molecular analysis of profiles of DNA samples
DNA fingerprinting refers to the molecular analysis of the profile of DNA samples. Short nucleotide repeats are important for DNA fingerprinting which vary in number from person to person but are inherited. These are variable number tandem repeats (VNTRs) and can be recognized only through molecular analysis of DNA samples.
