Statement-I : During oogenesis the 1st meiotic division occurs in secondary oocyte.
Statement-II : Diploid secondary oocyte gives rise to haploid second polar body and ovum.

Options

A. Both I and II statements are correct
B. Both I and II statements are wrong
C. Statement-I correct but II is wrong
D. Statement-I wrong but II is correct

Answer

To analyze the given statements regarding oogenesis, let's break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Oogenesis**:
- Oogenesis is the process of egg (ovum) formation in females. It involves several stages, including the development of oogonia, primary oocytes, secondary oocytes, and polar bodies.

2. **Analyzing Statement I**:
- **Statement I**: "During oogenesis, the 1st meiotic division occurs in the secondary oocyte."
- The first meiotic division actually occurs in the **primary oocyte**, not the secondary oocyte. The primary oocyte undergoes meiosis I to produce a secondary oocyte and a polar body. Therefore, this statement is **incorrect**.

3. **Analyzing Statement II**:
- **Statement II**: "Diploid secondary oocyte gives rise to haploid second polar body and ovum."
- The secondary oocyte is **haploid** (not diploid) as it has already undergone meiosis I. When the secondary oocyte undergoes meiosis II, it produces one ovum (which is haploid) and a second polar body (also haploid). Therefore, this statement is also **incorrect** because it incorrectly states that the secondary oocyte is diploid.

4. **Conclusion**:
- Since Statement I is incorrect and Statement II is also incorrect, the correct answer is that both statements are wrong.

### Final Answer:
Both Statement I and Statement II are incorrect.
