Placentation in tomato and lemon is

Options

A. parietal
B. free central
C. marginal
D. axile

Explanation

### Step-by-Step Solution

1. **Understanding Placentation**:
- Placentation refers to the arrangement of ovules within the ovary of a flower. The ovary is a part of the pistil, which also includes the stigma and style. The cavity inside the ovary is known as the ovarian cavity or locule, where the ovules are attached to a tissue called the placenta.

2. **Types of Placentation**:
- There are several types of placentation: marginal, parietal, free central, axile, and basal. Each type describes a different arrangement of ovules within the ovary.

3. **Identifying Placentation in Tomato and Lemon**:
- For the tomato and lemon, we need to determine which type of placentation they exhibit.
- The axile type of placentation is characterized by the presence of multiple locules (chambers) in the ovary, with ovules attached to a central column of placenta.

4. **Analyzing Tomato**:
- In tomatoes, the ovary is syncarpous (formed from multiple carpels) and is divided into two or more chambers. The ovules are arranged along the central axis of the ovary, which is indicative of axile placentation.

5. **Analyzing Lemon**:
- Similarly, lemons also have a syncarpous ovary that is divided into multiple locules. The ovules are attached to the central placenta, confirming that lemons also exhibit axile placentation.

6. **Conclusion**:
- Both tomato and lemon exhibit axile placentation, where the ovules are borne on a central column within a multilocular ovary.

### Final Answer:
The type of placentation in tomato and lemon is **axile placentation**.
