Solution

The correct option is C Polar body
During the process of oogenesis (formation of egg), following steps take place:
Oogonium undergoes ooctyogenesis to give primary oocyte.
Primary oocyte undergoes meiosis I to produce first polar body (which is later discarded) and a secondary oocyte.
The secondary oocyte then undergoes meiosis II (the maturation step) to produce second polar body (which is very small and is later discarded) and an ovum.
Therefore, the correct answer is option D.
