It seems that A should be the answer here, with the only note that it can't be constitutional delay. It looks more like familial short stature to me (though no family Hx available). What do u think, guys?

  #8

itīs A and itīs a familial short stature. Constitutional delay wonīt be A because the bone age (XRay) would be delayed.
