The answer is option D.

Apomixis can be defined as the replacement of the normal sexual reproduction by asexual reproduction. Apomixis mimics sexual reproduction without fertilization. The seed of the plant is developed without fertilisation. It can be observed in blackberries, mat grass, hawk weeds and many other. It can be useful in forming hybrid seeds. There are several ways of development of apomitic seeds. In some species , the diploid egg cell is formed without reduction division and develops into the embryo without fertilisation.
