The correct option is A endosperm
In most monocots and some dicot seeds, the endosperm acts as the food reserve. Hence they are referred to as albuminous or endospermic. E.g:- wheat, maize, barley, castor, etc.
In majority of the dicot seeds and some monocot seeds, the endosperm is completely consumed during seed development and the food is stored in other storage organs like cotyledons, perisperm (persistent nucellus in the seed) and also in hypocotyl (in Bartholettia). They are referred to as non-albuminous or non-endospermic seeds. E.g:- pea, groundnut, etc.
