Answer

To determine which flowers have a half inferior ovary, we can follow these steps:

### Step 1: Understand the Types of Ovaries
- There are three main types of ovary positions in flowers:
1. **Superior Ovary (Hypogynous)**: The ovary is located above the other floral parts.
2. **Half Inferior Ovary (Perigynous)**: The ovary is situated in between the other floral parts.
3. **Inferior Ovary (Epigynous)**: The ovary is below the other floral parts.

### Step 2: Identify the Half Inferior Ovary
- The half inferior ovary is specifically referred to as **perigynous**. This means that the ovary is partially enclosed by the floral parts, making it appear as if it is in between.

### Step 3: Recognize the Family with Half Inferior Ovaries
- The half inferior ovary is commonly found in the **Rosaceae family**. This family includes many well-known plants and flowers.

### Step 4: Provide Examples
- Examples of flowers with a half inferior ovary in the Rosaceae family include:
- **Plum**
- **Rose**
- Other members of the Rosaceae family.

### Step 5: Eliminate Incorrect Options
- When considering other examples such as mustard, guava, and cucumber, we can confirm that these do not have a half inferior ovary, thus they can be eliminated.

### Conclusion
- Based on the above analysis, the correct answer to the question "Half inferior ovary occurs in the flowers of" is **Plum** (and other members of the Rosaceae family).
