Answer:
C the identification of skeletons that are decades old
Step-by-step explanation:
Forensic anthropologists work actively in the identification and analyses of the gender, age, color, and ethnicity of skeletal remains that can be decades old or longer. A realistic aspect of their job entails going to the field to search out skeletal remains of people whom they are interested in and performing several scientific procedures on them to obtain full data and information about them.
Unidentified soldiers who died in battles can be traced and identified through this means.
