Solution

The correct option is D Seed coat
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 found in beet root and pepper seeds) and also in hypocotyl (in Bartholettia).
Nucellus is a mass of parenchymal cells present within the integuments of the ovule.
Seed coats are not known to store food.
