Which one of the following seeds is an example of non-albuminous seed?

The correct answer is Option (3) → Peas

During seed development the embryo feeds on the endosperm. In non-albuminous seeds the endosperm is used up completely, and the food is kept in the cotyledons. In albuminous seeds part of the endosperm remains in the mature seed.

Option (3) Peas — Correct. In pea no endosperm is left; the thick cotyledons store the food.

NCERT Extract:
Seed – “… Mature seeds may be non-albuminous or ex-albuminous. Non-albuminous seeds have no residual endosperm as it is completely consumed during embryo development (e.g., pea, groundnut). Albuminous seeds retain a part of endosperm as it is not completely used up during embryo development (e.g., wheat, maize, barley, castor).”
