The correct option is C Ricinus
The seed is endospermic in Ricinus. The fruit is a spiny, greenish capsule containing large, oval, shiny, bean-like, highly poisonous seeds with variable brownish mottling. Castor seeds have a warty appendage called as the caruncle, which is a type of elaiosome. The seeds are endospermic or albuminous where the embryo is embedded in the endosperm and nucellus, which the seedling will use upon germination.
Therefore, the correct answer is option C.
