(A) In the development of a typical angiosperm female gametophyte (embryo sac),the nucleus of the functional megaspore undergoes three successive mitotic divisions to form $8$ nuclei.After the $8$-nucleate stage,cell walls are laid down,leading to the organization of the typical female gametophyte.Specifically,$3$ nuclei move to the micropylar end to form the egg apparatus,and $3$ nuclei move to the chalazal end to form antipodal cells.The remaining $2$ nuclei,known as polar nuclei,migrate from each pole (one from the micropylar end and one from the chalazal end) to the centre of the embryo sac.Therefore,$1$ nucleus from each pole migrates to the centre,making a total of $2$ polar nuclei in the central cell.

How many polar nuclei migrate to the centre of the developing female gametophyte from each pole of the female gametophyte?
