Solution
The correct option is A Humerus
Most of the cartilage in embryo is replaced by bones in adults. The cartilage in embryo gradually calcifies. During calcification, chondrocytes are replaced by bone cells. Epiphyseal plate is a thin plate of cartilage that is present at the ends of growing bones. This is completely ossified when the bone around it is fully grown. However, this is not seen at 2 places, cartilaginous rings in the trachea and the rib cartilage between ribs and sternum and in articulating joint such as humerus. Thus, the correct answer is 'Humerus.'
