In this question, it asks the sign to confirm his growth is complete so I go with D.

ok when the growth is complete there won't be any cartilagenous plate.
D happens in achondroplasia and this case is proportionate.

D only suggests tht there is calcification in the epiphysis....thts a normal phenomena,during growth.....never said tht the epiphysis is completely calcified!
but the absence of epiphyseal cartilaginous plate....leaves no doubt tht the growth is indeed complete,coz this is when the epiphysis on X-rays appear fused!
answer is A
