Solution

The correct option is A Cotyledons
In dicotyledons, the two apical cells first divide by longitudinal division and then by transverse and periclinal division. So there forms a sixteen celled globular embryo or pro-embryo.
Due to the differentiation of the cotyledons, the pro-embryo becomes heart shaped.
