Options

Answer

D

Explanation

Majority of dicot seeds (e.g., pea, gram, bean, mustard,groundnut) and a few monocut seeds (e.g., orchids, Sagittaria), are called nonendospermic or exalbuminous seeds because the endosperm is consumed during seed development and the food is stored in cotyledons and other region.
