Bicarpellary ovary with partietal placentation and false septum is found in :-

Options

A. Cruciferae
B. Leguminosae
C. Malvaceae
D. Compositae

Answer

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Bicarpellary**: This refers to an ovary that has two carpels or pistils. In flowering plants, the female reproductive part is called the gynoecium, which is made up of one or more carpels.
- **Placentation**: This is the arrangement of ovules within the ovary. Different types of placentation exist, and in this case, we are focusing on parietal placentation.

2. **Identify Parietal Placentation**:
- In parietal placentation, the ovules are attached to the walls of the ovary rather than being arranged in the center. This means that the ovules are located at the periphery of the ovary.

3. **Understand False Septum**:
- A false septum refers to a condition where there is not a complete septum dividing the ovary into separate chambers, but there may be a small amount of septum present that gives the appearance of division.

4. **Determine the Family**:
- The question asks for a plant that has a bicarpellary ovary with parietal placentation and a false septum. The family that exhibits these characteristics is the **Brassicaceae** family, also known as the crucifer family.

5. **Provide an Example**:
- An example of a plant from the Brassicaceae family that has these characteristics is **mustard**.

### Final Answer:
Bicarpellary ovary with parietal placentation and false septum is found in the **Brassicaceae family**, with **mustard** being a specific example.
