Answer:
The correct option is D. 18 year old male
Explanation:
The epiphyseal plate can be described as a disc of cartilage that is required for the growth of bones. The epiphyseal plates get fused in females at a very early age, most probably between the ages of 13 to 15. In males, the epiphyseal plates fuse a litter later at about 15 to 18 years.
Hence, the presence of epiphyseal plates in the femur would prove that it was present in an 18-year-old male.
All the other options would be false because they won't contain an epiphyseal plate.
