In recent times, this analysis technique is used to identify victims of cold cases, mass disasters (tsunami and earthquakes), historically important cases (war soldiers) and cases with limited biological material. Another advantage of mtDNA is that it can be isolated from samples like hair shafts, bones and teeth. Thus, investigators can study these samples by extracting mtDNA. So I would say B.
