Answer

Correct option: D.
Castor
Castor bean seeds contain an elaiosome $($caruncle$)$ which are fleshy structures that are attached to seeds of many plant species.
They are rich in lipids and proteins that attract ants, which disperse the seed $($myrmecochory$).$
Castor bean seeds are endospermic which means, the endosperm is the major storage tissue.
In perispermic seeds $($castor$),$ diploid maternal food storage tissue originates from the nucellus.
