Final answer:
The femur is the most useful bone for determining an individual's height in forensic anthropology as per the "Sherlock Bones" Lab.
Step-by-step explanation:
According to the "Sherlock Bones" Lab, which is related to the field of forensic anthropology, the most useful bone for determining the height of an individual when they died is the femur. This is because the length of the femur is directly correlated with a person's overall height. Other bones, such as the skull, pelvis, or sacrum, do not have as direct a correlation and can be less reliable for this kind of measurement. Forensic anthropologists use a variety of bones to determine not just height but also age, sex, and race.
