A young man whose documents claim he is under 18 years is produced before a magistrate for age verification. Radiographs show complete fusion of the medial (sternal) end of both clavicles with the shaft, but the iliac crest apophysis is also completely fused. The MOST appropriate conclusion is that his age exceeds:
- A 17 years
- B 19 years
- C 21 years ✓
- D 25 years
Correct answer: C. 21 years
Explanation
The medial end of the clavicle is the last primary epiphysis in the body to unite, fusing between 21 and 25 years. Its complete union is therefore accepted in Indian forensic practice as proof that the individual has crossed 21 years, the age relevant to many statutory provisions. Iliac crest fusion completes between roughly 20 and 25 years and adds supporting evidence. Options below 21 years contradict the presence of full sternal-end fusion, which does not even begin until about 18 years.
