D.

Answer

To solve the problem of choosing the best suitable Venn diagram for the words "Bus," "Engine," and "Piston," we can follow these steps:

### Step 1: Understand the Relationships
First, we need to analyze the relationships between the three words:
- A **Bus** is a type of vehicle that contains an **Engine**.
- An **Engine** is a machine that can have components like a **Piston**.

### Step 2: Identify the Hierarchical Structure
From the relationships identified:
- The **Bus** is the largest category that includes the **Engine**.
- The **Engine** is a subset of the **Bus** and includes the **Piston** as a component.

### Step 3: Draw the Venn Diagram
Now, we can represent these relationships in a Venn diagram:
- Draw a large circle for **Bus**.
- Inside the **Bus** circle, draw a smaller circle for **Engine**.
- Inside the **Engine** circle, draw an even smaller circle for **Piston**.

### Step 4: Label the Diagram
Label the largest circle as "Bus," the middle circle as "Engine," and the smallest circle as "Piston."

### Conclusion
The best suitable Venn diagram would show:
- A large circle (Bus) containing a smaller circle (Engine), which in turn contains the smallest circle (Piston).
