Solution
The correct option is D Citrus
Presence of more than one embryo inside the seed of a flowering plant, is called polyembryony. It is more common in gymnosperms than angiosperms. In angiosperms, it is present as an unusual feature in few cases like Citrus.
It is due to formation of more than one egg in embryo sac, or more synergid cells, integument or nucellus cells which may develops into an embryo. e.g. Orange lemon groundnut mango onion etc.
In Citrus many embryos are formed from the structures outside the embryo (like nucellus). So, the correct answer is "option A"
