The ovary is half inferior in:

Options

A. Mustard
B. Sunflower
C. Plum
D. Brinjal

Answer

To determine which plant has a half inferior ovary, we will analyze the options given: mustard, sunflower, plum, and brinjal.

### Step-by-Step Solution:

1. **Understanding the Types of Ovaries**:
- The ovary can be classified as superior, half inferior, or inferior based on its position in relation to other floral parts (sepals, petals, and stamens).
- A **superior ovary** is located above the attachment of other floral parts.
- An **inferior ovary** is located below the attachment of other floral parts.
- A **half inferior ovary** (or **periginous flower**) is positioned in between, where the ovary is partially embedded in the receptacle.

2. **Analyzing Each Option**:
- **Mustard**: The ovary is superior, meaning it is located above the other floral parts. Therefore, this option is incorrect.
- **Sunflower**: The ovary is inferior, meaning it is located below the other floral parts. This option is also incorrect.
- **Plum**: The ovary is half inferior. This means it is positioned in the middle, making it the correct option.
- **Brinjal**: Similar to mustard, the ovary is superior, which makes this option incorrect as well.

3. **Conclusion**:
- Based on the analysis, the correct answer is **C. Plum**, as it has a half inferior ovary.
