After completion of second meiotic division of the secondary oocyte and result in the formation of a `ul((A))` and a haploid `ul((B))`.

Answer

**Step-by-Step Solution:**

1. **Understanding Oogenesis**: Oogenesis is the process of egg (ovum) formation in females. It begins in the fetal ovary and involves several stages, including the formation of primary oocytes.

2. **Primary Oocyte Formation**: At birth, females have a large number of primary oocytes, which are arrested in the diplotene stage of prophase I of meiosis. This means they are not yet fully developed into eggs.

3. **First Meiotic Division**: During each menstrual cycle, a primary oocyte completes its first meiotic division, resulting in a secondary oocyte and a first polar body. The polar body is a small cell that typically degenerates.

4. **Secondary Oocyte and Fertilization**: The secondary oocyte is released during ovulation. If fertilization occurs, the secondary oocyte will undergo the second meiotic division.

5. **Second Meiotic Division**: The second meiotic division of the secondary oocyte results in two cells:
- **A (Ootid)**: This is the mature egg (ovum) that has a haploid nucleus.
- **B (Second Polar Body)**: This is a smaller cell that is also haploid and usually degenerates.

6. **Conclusion**: Therefore, after the completion of the second meiotic division of the secondary oocyte, we have:
- A = Ootid (the mature egg)
- B = Second Polar Body (haploid)
