Drupes develop from
(a) monocarpellary superior ovaries
(b) monocarpellary inferior ovaries
(c) bicarpellary superior ovaries
(d) bicarpellary inferior ovaries

Options

A. monocarpellary superior ovaries
B. monocarpellary inferior ovaries
C. bicarpellery superior ovaries
D. bicarpellery inferior ovaries

Answer

To solve the question regarding the development of drupes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Drupes**:
- A drupe is a type of fruit that is characterized by a fleshy outer layer and a hard stony covering enclosing the seed. Common examples include mangoes, coconuts, and plums.

2. **Identifying the Type of Ovary**:
- Drupes develop from specific types of ovaries. The options provided in the question include different configurations of monocarpellary and bicarpellary ovaries, as well as their positions (superior or inferior).

3. **Monocarpellary vs. Bicarpellary**:
- Monocarpellary ovaries consist of a single carpel, while bicarpellary ovaries consist of two carpels.
- Drupes typically develop from a single carpel, making monocarpellary ovaries more relevant to the formation of drupes.

4. **Superior vs. Inferior Ovaries**:
- Superior ovaries are located above the attachment of other floral parts, while inferior ovaries are located below them.
- Drupes are known to develop from superior ovaries, as seen in many examples of drupes.

5. **Conclusion**:
- Based on the characteristics of drupes, they develop from monocarpellary superior ovaries. Therefore, the correct answer to the question is option (a) monocarpellary superior ovaries.

### Final Answer:
(a) monocarpellary superior ovaries
