Options

A. acropetal manner
B. basipetal manner
C. one plane
D. none of these

Answer

To answer the question about the arrangement of leaflets in a pinnate compound leaf, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Leaf Structure**:
- First, we need to understand the basic structure of leaves. Leaves can be classified into simple and compound leaves. In simple leaves, there is a single lamina, while in compound leaves, the lamina is divided into multiple leaflets.

2. **Identifying Pinnate Compound Leaves**:
- Pinnate compound leaves are characterized by having leaflets arranged along a central axis called the rachis. This arrangement resembles a feather, which is why it is referred to as "pinnate."

3. **Arrangement of Leaflets**:
- In a pinnate compound leaf, the leaflets are borne on either side of the rachis. This means that they are arranged in a single plane, extending outwards from the central axis.

4. **Examples of Pinnate Compound Leaves**:
- A common example of a plant with pinnate compound leaves is the neem tree. The leaflets of the neem are arranged in a single plane along the rachis.

5. **Conclusion**:
- Based on this understanding, we can conclude that in a pinnate compound leaf, the leaflets are borne in one plane.

### Final Answer:
The correct answer is option C: "one plane."
