Reason : Primary function of formation of polarbodies is to bring haploidy of ovum .

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion .
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False .
D. If both Assertion & Reason are False.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "During oogenesis polar bodies are formed." This is true. Oogenesis is the process of forming female gametes (ova), and during this process, polar bodies are indeed produced.

2. **Understanding the Process of Oogenesis**: Oogenesis begins before birth and continues through a female's reproductive life. It involves meiosis, which is the type of cell division that reduces the chromosome number by half to produce haploid cells.

3. **Formation of Polar Bodies**: In oogenesis, during the first meiotic division, one primary oocyte divides to produce one large ovum and one small polar body. The polar body is a byproduct that typically does not develop into a functional egg. A second polar body is formed during the second meiotic division, which occurs after fertilization.

4. **Understanding the Reason**: The reason states that "The primary function of formation of polar bodies is to bring haploidy of ovum." This is also true. The formation of polar bodies is essential for ensuring that the ovum has the correct haploid number of chromosomes (half the diploid number).

5. **Conclusion**: Both the assertion and the reason are correct, and the reason correctly explains the assertion. Therefore, the correct answer is that both statements are true, and the reason is the correct explanation for the assertion.

### Final Answer:
Both the assertion and the reason are correct, and the reason is the correct explanation of the assertion.
