A characteristic feature of Ovary of Mustard is :-

Options

A. Presence of false septum
B. Axile placentation
C. Epigynous
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a characteristic feature of the ovary of mustard. To answer this, we need to focus on the structure and arrangement of ovules in the mustard ovary.

2. **Identifying the Type of Placentation**: In mustard, the type of placentation is crucial. Placentation refers to the arrangement of ovules within the ovary. The characteristic feature of mustard ovary is that it exhibits parietal placentation.

3. **Defining Parietal Placentation**: Parietal placentation means that the ovules are attached to the inner wall of the ovary. This is a key feature that distinguishes it from other types of placentation.

4. **Examining the Structure of the Ovary**: The mustard ovary is described as being two-chambered. However, it appears two-chambered due to the presence of a false septum. This false septum is also known as a replum, which divides the ovary into two sections but does not create true chambers.

5. **Conclusion**: Therefore, the characteristic feature of the ovary of mustard is the presence of a false septum (replum) and parietal placentation. The correct answer to the question is the presence of a false septum.

**Final Answer**: The characteristic feature of the ovary of mustard is the presence of a false septum (replum).
