Final answer:
Based on the narrow and tall pelvic bones, the forensic anthropologist can conclude that the victim was most likely a man.
Step-by-step explanation:
When analyzing skeletal remains, one of the key determinations a forensic anthropologist has to make regards the sex of the individual. In this case, Bruno has observed narrow and tall pelvic bones, which are characteristic features of a male pelvis. Female pelvic bones tend to be wider and not as tall, to accommodate childbirth. Therefore, based on this evidence, Bruno can most likely conclude that the victim was a man, making the correct answer D. The victim was a man.
