The correct option is D None of the above
Perisperm, the nutritive tissue of the seed which originates from the tecrine or nucellus, outside the embryo sac. It consits mainly of thin-walled parenchymatous cells rich in starch or oil, and, together with the endosperm within the embryo-sac, constitutes what was formerly known as albumen. With the exception of some Alismaceas and Orchidaceas, almost all spermaphytes have perisperm in the early stages of the development of the seed; but in 'exalbuminous' seeds it, together with the endosperm, is absorbed before the seed is ripe.
