Solution
The correct option is A Citrus
In seeded plants after fertilization, ovules mature into seeds. Normally, a single embryo is present in each seed but sometimes more than one embryo is present in a seed. This condition is known as polyembryony. Nucellar polymbryony is a type of adventive polyembryony, in which some of the nucellar cells surrounding the embryo sac start dividing. Then it protrudes into the embryo sac and develop into the embryos. In such species, each ovule contains many embryos. Nucellar polyembryony is found in many of the citrus and mango varieties.
