(d)

Occurrence of more than one embryo in a seed is reffered as polyembryony. In many Citrus and mango varieties, some of the nucellar cells surrounding the embryo sac start dividing, protrude into the embryo sac and develop into the embryos. In such species, each ovule contains many embryos (nucellar polyembryony).
