Options

A. Spermatogonia `rarr` Spermatids `rarr` Secondary spermatocytes `rarr` Primary spermatocytes `rarr` Sperms
B. Ova
C. Oogonia
D. Sperms.

Answer

**Step-by-Step Solution:**

1. **Understanding Polar Bodies**: Polar bodies are small cells that are produced during the process of oogenesis, which is the formation of egg cells (ova) in females.

2. **Oogenesis Process**: During oogenesis, a primary oocyte undergoes meiosis. This process involves two meiotic divisions:
- The first meiotic division results in one large secondary oocyte and one small polar body.
- The second meiotic division occurs only if fertilization takes place, producing another polar body and the mature ovum.

3. **Formation of Polar Bodies**: Typically, one primary oocyte will produce:
- One ovum (the functional egg cell)
- Two to three polar bodies (which are non-functional and eventually degenerate).

4. **Conclusion**: Since polar bodies are specifically associated with the formation of ova during oogenesis, the correct answer to the question is that polar bodies develop during the formation of ova.

**Final Answer**: Option B - Ova.
