Correct answer: D. Polar body
- A. Ovum
- B. Oogonium
- C. Follicle cell
- D. Polar body
Explanation
Inside the ovary, during the process of oogenesis, the primary oocyte undergoes the first meiotic division, resulting in the formation of two haploid cells. These cells are the secondary oocyte and a smaller cell called the first polar body. The first polar body is a smaller cell that contains a portion of the genetic material but minimal cytoplasm. The polar bodies typically do not play a direct role in fertilization and are eventually broken down or reabsorbed.
