(A)If you remove the package specification, then the package body and the stand alone stored function CALC_HEIGHT are removed.
(B)If you remove the package body, then the package specification and the stand alone stored function CALC_HEIGHT are removed.
(C)If you remove the package specification, then the package body is removed.
(D)If you remove the package body, then the package specification is removed.
(E)If you remove the stand alone stored function CALC_HEIGHT, then the METRIC_CONVERTER package body and the package specification are removed.(AB).The stand alone function CALC_HEIGHT cannot be created because its name is used in a packaged function.
