The answer is A, because the 'filling' is the jelly like cytoplasm and the edge is the cell wall
Polar bodies are considered byproducts of oogenesis. They are lacking cytoplasm and are much smaller than a regular egg cell. Typically they disintegrate after meiosis.

Therefore it is most likely lacking nutrients, and does not have the necessary resources for a healthy baby to develop.
